Door lock actuators are an electronic component found on vehicles equipped with power door locks. They are the electronically controlled actuators in every single door that are responsible for locking and unlocking the power door locks when the switches are pressed. When they fail or have issuesthey can disable the power door lock feature, which can be a major inconvenience to the driver. Usually a bad or failing power door lock actuator will produce a few symptoms that can notify the driver of an issue that should be serviced.
Unusual noises coming from inside the door are one of the first symptoms of a potential problem with a power door lock actuator. Most power door locks operate using gears or motors that may quietly whir, or make noise when they operate. Those noises are normal. However, if the noise suddenly becomes louder or more pronounced, then this may be an indicator that the gears or motor are becoming worn out. The noises may get louder until the actuators eventually fail. Another symptom of a potential problem with the power door lock actuators are door locks that behave erratically.
If the actuators have any sort of internal or wiring issue, it may cause them to rapidly lock and unlock unexpectedly, or cause them to function intermittently. Another symptom of a potential problem with the door lock actuators are power door locks that do not function.
If the door lock actuators fail, they will disable the power door lock feature from working. This will require the driver to use the key to lock or unlock the doors, and can disable the power door locks completely for vehicles that do not use a traditional key, such as newer luxury vehicles.
The power door lock actuators are a simple component, but are critical to the operation of the power door locks - which are among the most commonly used features of any vehicle. For this reason, if you suspect that one or more of your power door lock actuators may be having an issue, have the vehicle inspected by a professional technician, such as one from YourMechanic to determine if you need a door lock actuator replacement.

I'm posting this, because I was stuck in a similar dilemma just a few days ago: drove to the neighborhood market slightly late in the evening around 10 pm to grab a quick dinner, after dinner I walked up to the car and pressed the unlock button - no response, I walked closer and pressed again, nothing - for a while I thought maybe I was pressing the wrong button It was dark so I could'nt actually see the buttons.
So used my cellphone as a torch and pressed again - nothing at all - I was more confused than worried - was'nt really expecting something like this Went back into the market relatively well lit and shielded from the wind and did a quick investigation of the remote - and noticed that the small really really minuscule - the size of a needle head light at the bottom of the remote was'nt lighting up - figured the battery was dead - opened the remote removed the battery and kinda rubbed it between my palms - hoping the warmth would revive the battery enough to unlock my car - but to no avail Luckily the market is within the colony and relatively safe even at night, so after spending about half an hour trying to get the car unlocked with the help of a couple of shopkeepers and security guards, I left the car parked there and decided to go back home and fetch the spare remote - walked back home, picked up a torch and the spare remote and then walked back to the market no convenient public transport in gurgaon at night!!
Sure enough the car unlocked without a hitch with the spare remote of course and I drove back home. Got the battery replaced the next day for 80 bucks from the local watch repair guy and the remote is as good as new Well I was lucky enough that this happened close to home and I had the spare remote handy, but should'nt these remotes have some kind of a low battery warning so that people aren't stranded because of something so ridiculously trivial. Also, what is the recommended procedure incase someone is stuck - is it better to open the car with the key and then somehow disarm the sirens?
Like I said I was lucky to be able to access my spare remote - but I would like this thread to act as a reference for others stuck in a similar situation which I'm sure is not that uncommon. Last edited by adisag : 3rd December at Yes, sometimes it is a problem. But you can use the key to unlock the doors, but you will not be able to start the car as the immobilizer will still be active.
I was in a similar situation. So now I keep a spare battery in my car at all times. In case the battery dies, I can use the spare in the car. Originally Posted by speedmiester. Originally Posted by adisag.

We had been to late night movie and after the movie when i approach the car and trying to release the lock for some reason my keyless entry just didnt bother to work.
I was shocked and confused as to what to do. But no, it was not working. So i made a mistake by trying to unlocking the door using key and there it goes The security out there was staring at me as if i have come to steal the car or something, luckily he didnt ask any questions. Such a annoying situation. After 15 minutes of sturggle things were under control.
The best part, next morning i had parked my car down the road which is easily around mtrs from my place and spare key was at home. Now picture a situation; I was near the car which was locked and it was parked almost mtrs away from my house, I called up my people at home and asked them to take the spare key and press unlock button from there and i held the phone near the car and BOOOMMMM I had heard about something like this, but when i tried it personally it was amazingly super.
This is one solution I found on the web. This has happened many times before so I wasn't too worried - just open the door with the key and when you put the key in the ignition it should stop the alarm and let you re-sync as detailed above.Problems with remotely locking and unlocking a car's doors can be frustrating.
Your Toyota Corolla is likely to experience remote locking issues from time to time just like all other vehicles of different makes and models. Whether your doors never unlock remotely or unlock only sometimes, you can do some quick troubleshooting to find out if the problem is with your Corolla or the remote keypad.
Most keypads operate on AG13 button-cell batteries. These batteries are typically used in power laser pointers and other small electronic devices. If your vehicle does not respond at all when you attempt to lock it remotely -- that is, the horn won't honk and the doors won't lock -- replace the battery in your keypad.Maruti Remote Central Lock Problem. Siren Alarm Sound को कैसे Mute करे
If you press the "lock" button on your keypad and none of the doors lock, but you are able to honk the horn, it is likely that internal wiring is the cause. This indicates that the Corolla is receiving the lock signal from the keypad but cannot execute it. Unless you are an experienced mechanic, you'll need to take the car to a dealership or repair shop to fix this problem. If you are seeing an inconsistent response, where sometimes the door locks remotely and sometimes it won't, the keypad itself or the keypad receiver installed in your vehicle may be to blame.
Installing replacement parts yourself can be done with minimal time and effort.
Many auto repair shops and online outlets sell do-it-yourself kits for this situation.

Symptoms of a Bad or Failing Door Lock Actuator
Photo Credits car keys image by bright from Fotolia.My car won't start, the power locks etc don't work, and the battery won't jump. It seems to me that this means the batter is just kaput and I need a new one, but I thought I would ask around before I dropped money on a battery when it might be the starter, ignition, or whatever. It can't be the battery if you can't even jump it, unless you hooked up the jumpers backwards or something.
But you really should not jump start a car unless it is an emergency, since if you do get it started, charging the dead battery will likely fry the alternator. There are accessories that don't need the ignition switch to be on, and if they don't work, it is not likely the ignition switch. The most common would be corroded battery terminals, loose ground strap, or blown inline fusible link. You are seeing power failures in both the engine and chassis electrical circuits so the fault must be in the main power circuit that supplies them.
You will not have lost money if the battery tested "bad. If any problem persists new battery or not inspect per above and post new description--I doubt very much you will need to. Remember to reset clock and it will take a little time for the car to retrain itself after the power outage. Inexpensive battery cables create too much electrical loss. Good battery cables will have a low AWG wire size stamped on the outer insulation of the cables.
The lower the number the larger the woven electrical wires inside the cable. A volt meter will not tell you if your battery is bad.
You can have a battery show 12 volts and not have any amps. The battery needs to be load tested. Just about any auto parts store will do this. If you have a volt meter you can check if the battery is bad that way. You hook it up to the positive and negative terminals and if it reads under If it reads around A new battery should read around So its either your battery or alternator. Good luck. Trending News.

Even if it's just a dead battery, you can pretty much guarantee that your car doors will fail to unlock with the remote at one time or another. While there are a few different reasons that a keyless entry remote might stop working, most of them are pretty easy to check yourself.
Other key fob remote problems are more complicated, but it's still possible to fix them. Here are the five things you'll want to check first when your remote stops locking or unlocking your car doors:.
However, there could also be a mechanical or electrical problem with the door locks. At this point, you'll want to check and make sure that your physical key, or emergency valet key, is able to work the locks. If you don't have a spare remote, you may be able to buy a used one or get one from your local dealership. Your local dealership may also have a universal remote they can use to check if your remote lock mechanism works. Some cars have push-button ignitions that only operate when the key fob is close by.
These vehicles still usually have a physical key for locking and unlocking the doors, but it may be hidden. The key fob will often have a hidden key inside, so if you don't have a physical key for your vehicle, then check the fob for a release button or switch. The other issue you may run into is that some car doors don't have any visible place to insert a key. Most of these vehicles still have a keyhole, but it may be hidden behind a trim piece near the door handle.
In that case, you will want to look for a trim piece with a small slot in it, which you will have to pry away to access the keyhole. Prying away a trim piece like this does carry some danger of damaging the paint on the car door or door handle, and you can also dent or bend the trim piece. So if you aren't comfortable, and there isn't an emergency that requires you to get inside your car immediately, you may want to consult a professional.
If you are able to lock and unlock the doors with the physical key, then the locks are probably fine mechanically. However, there could still be an electrical problem. You can rule part of this out by locking and unlocking all of the doors via the physical master control inside the vehicle, which would indicate that the electronics are fine. You can check behind and under the dashboard for loose wires, but don't connect or plug anything in if you aren't able to verify that it's actually the wireless door lock receiver.
There are a few ways to determine the type of battery you need. It may say in your manual, or you can contact a local dealer.When I hit lock twice like the owner's manual says I get no audio response. My dealer says this is normal on some models I think not. What do you think? James answered 7 years ago. I think the dealer is right.
The Elantra does not chirp the horn when locking. Harsha answered 7 years ago. Although it doesn't chirp, it is more of an annoying honk. Corrie answered 6 years ago. I have a Elantra, and it definitely honks when you press the fob a second time. The dealer is blowing smoke up your ass hoping you don't come in for warranty.
Check Harsha's comment above about muting to see if there is an issue or if it's something simple. On my daughter's Elantra Limited, an under-hood switched circuit closed when hood is closed can bend down away from the hood cause the circuit to remain open.
The switch is located toward the right sideof the car near the radiator. Withthe hood open, try holding the switch closed and locking the car with the remote.
If the car chirps you need to mend the switch bracket up a bit. I need to do it periodically on her car. Alec answered 4 years ago. My horn doesn't chirp when it is below freezing.
It works diring warmer months, but not in the cold? Greaver answered 3 years ago. Ok I have been driving myself crazy trying to fix it myself. Tried reprogramming,checked all sensors on doors and hood. All good. Checked alarm it was not working. I locked the car and tried to open each door from outside.
What Causes a Car's Electrical System to Suddenly Stop Working?
My back door was not locking. Played with the latch locked it by hand. Used fob to lock all of the doors and it flashed and beeped. Alarm is working again. So can't use back door right now until I figure out how to fix latch.Any type of automotive repair can be costly.
If your automatic lock isn't working, here are four easy steps to repair car door lock. It should be the most obvious, but most of the time we simply don't think of the auto key lock on our keychains. Called a key fob, it is operated by a battery that does wear out after several years of use. Replace the battery, then check it to see if it is in working order again.
Before rushing to rip off the door panel, and replacing wires and parts, check the other locks. Do they work? If not, then you may have a blown fuse. If they do work, the problem is most likely in the door lock solenoid. While the key is in, work the door lock manually up and down while using the auto lock at the same time.
If the lock tries to move, then it is a frozen lock mechanism. Hold the lock button down while you slowly open and close the door. If the lock works, then you have a broken or frayed wire that needs to be changed or repaired.
