The light should blink all the time without running down your battery, that tells you it's working. pull one fuse at a time and see if any are blown for your locks. you may need a new battery.

Door locks and unlockgo down road


Before you begin to diagnose the problem, make sure you take some time to look over the problem and test out all of your door locks. Also, spend time "listening" to your door locks. Do you hear a buzzing sound? Does the lock sound like it is just getting stuck? Here is a break down of what to look for with different combinations of door lock failure. Four Doors/Multiple Doors Fail to Lock/Unlock If you have multiple doors or if all four doors fail to lock/unlock you could be looking at the worst case scenario - a wiring issue. Before you take it in though, try to change out the fuse and try manually locking the door. Each of these things will help you and/or your mechanic start narrowing down the problem.
A word of caution, if it is an electrical wiring issue, don't consider tackling it on your own unless you have lots of time and patience. These types of repairs can take a lot of time and create quite a bit of stress.
One Door Doesn't Lock/Unlock If you have one door that doesn't lock or unlock, you probably have either an actuator motor issue and/or the door lock is simply getting stuck. Here is how you fix it.
  1. Remove the door panel and look over the locking mechanism.
  2. If the lock is free from obstructions, it could be the actuator. Order a new motor from a Toyota authorized dealer like ours: parts.olathetoyota.com
  3. After you have the replacement part, it is simply a swap and reassemble process. Just make sure you take your time and don't bend anything. Surprisingly, the door locking mechanism can get out of whack quickly if things don't line up quite right. Take your time.
  4. Replace the door panel and pat yourself on the back.
Remote Lock/Unlock Fails, Button on Door Works If you can manually lock your doors or the lock/unlock button works inside the car, yet the key fob won't unlock the doors, you have a simple issue. Simply put, the battery is dead in your key fob. You can either open the key fob (squeeze on the sides) and get a replacement battery from a store. Or, you can bring your car to the dealer and they can replace it quickly and easily.
Power door locks sure are convenient, yet they are incredibly frustrating when they don't work. Hopefully one of these instructions above solved your problem.

Mercedes c class 2001 elegance, key fob not working everytime its pressed. I have had the batteries checked and they are still working fine, any advice as to what is causing this?


Most likely needs to be re matched to the car.

Two bits of info off the net for you

C CLASS (1993-1997), E CLASS (1995-1997), SLK (1996-)
Procedure
1. Point the remote control at the receiver - this should be located in the driver's door handle or next to the boot lock button.
2. Press the lock/unlock button.
3. Within 30 seconds manually lock or unlock the vehicle using the passenger's door lock or the boot lock.
Alternative method
Procedure
1. Point the remote control at the receiver - this should be located in the driver's door handle or next to the boot lock button.
2. Press the lock/unlock button.
3. Within 30 seconds, switch the ignition ON.
Alternative method
Procedure
1. Point the remote control at the receiver - this should be located in the driver's door handle or next to the boot lock button.
2. Press the lock/unlock button.
3. Within 30 seconds, turn the ignition switch to position II.


and

1. Place key in ignition lock and turn to position 2 [all ignition lights on]
2: Turn key to off position and remove from ignition.
3. Within 10 seconds:
3a: press the Close [Lock] button and hold it down
3b: while the Close button is still depressed simultaneously press the Open [Unlock] button. Press and release the Open button 5 times [still holding the Close button down]
3c: Release both the Close and the Open buttons at the same time, and immediately push any of the two Open buttons once [i.e. either the Open doors or the Open Tailgate]

This information is for the resetting of a previously synchronised key to match the security system after batteries have been removed or replaced. This information does not work with new keys which it seems must be taken to a person with a key synchronisation device [or a super-ripoff-expensive MB dealer]

hope this helps

2002 Dodge Caravan 3.3 liter 6, 36,000 original miles..Car runs fine, but headlights and E-flashers just started blinking on & off, alternately, like a police car would do. Kept on, no change, even...


sounds like you have a security problem, (antitheft) , when it acts up take the key and put it in the outside door lock switch with the door shut and window down and lock and unlock the drivers door with the key,it should quit, if not try locking and unlocking car with key fob(remote lock,unlock switch on key chain), if that dont work , you have further prob. with security system and take it to a shop. if it quits with the key process and then comes back on , the sensitivity might be to high. does the horn go off with the lights?

1993 Nissan Altima The security light is blinking and the car wont turn over. it has a good battery. Is the flashing security light preventing the car from turning over?


Yes, the security system shuts power to the starter and fuel pump. You can try disarming by unlocking and locking the doors the power door locks switch (depends on model). Place the key in the ignition and set to ON, ALL doors closed!! Cycle the locks using the power locks button on the driver's door "lock" then "unlock" if this doesnt work, try same method with the ignition OFF. Otherwise your security system is malf.

The security red light blinks even if you lock or unlock the car.


Check your security to see if its working by, roll the passenger window down, lock the car as normal like you are going in the store but your window will be down. take your keys inside the house go back out after a few minutes, reach inside the passenger door open the door nad alarm should sound, if this works everything is working fine. security light should blink normal as you enter or exit the car, This sounds normal to me.

Remoye keyless entry


Try spraying a penetrating spray (WD-40 or similar) into key holes on door, and up into latch area. You may have to do it numerous times before things will loosen up. You may need to remove the door panel, to ensure that you've loosened up all the pivot spots on the linkages but I would certainly make sure the linkages going to the locks are all moving freely before I change a power lock motor. Sometimes spraying the lube, and assisting the motor by manually lifting/pushing down button at same time as flipping the switch, will aid in loosening it too.
