    The master door locks do not work any longer. I have have to unlock the front doors with the key. Is there a leak in the master locking system?

I would order a new door lock panel that goes on your driver side door, you mite be able to get a used one by looking on line. It sounds like the contacts have gone bad. I have replaced the control panel before. To fix one of these if your really trying to fix it your self is not worth the time and technical skill you need to do this. Its easier and quicker to just go to junk yard or part store and get a new one.

2002 Sequoia automatic locks/auto lock buttons no longer work - all doors affected


You possibly need to reprogram the lock system to match your fobs.
If it unlocks by the interior switches then its the fob programming. This site is one example you can look for. http://www.chadspictures.com/automotive/How-To-Program-Toyota-Key-Fob/ If this is not the issue the computer that does the door locks could have died or you can look for the door lock fuse or a cut or pinched wire (due to other damage in an accident or from prior mods you did). Other possibilities include intermittent door solenoids if you can use the interior switch you can click it open and closed until you find the one that does not work every time. Change it out as it can leave your vehicle unlocked or it might interrupt the system. worst case it could be the chassis computer this site sells some http://www.automotix.net/usedautoparts/2008-toyota-sequoia-chassis_computer-product-i88489256n.html?gclid=CKfowo60gb8CFQQOaQodGqUArQ . If the shift lock system is screwed up it could be casing issues also but that's a long shot.

Horn honks doors lock be self


does this help? look in owners manual for how to turn "on or off" the auto lock feature.


Automatic Door Lock/Unlock
The automatic door unlock function is a vehicle personalization feature with the following 3?programmable modes of operation:
1. All: All of the doors will automatically unlock. 2. Driver: The driver's door will automatically unlock. 3. None: The doors will need to be unlocked by a door switch command or by pressing the the lock button on the RKE transmitter. The All or Driver modes may also be programmed as to when the automatic door unlocking will occur.
1. Key Off: The door(s) will unlock when the key is turned off. 2. Shift to Park: The door(s) will unlock when the vehicle is shifted into P (Park). The delay lock function may be enabled or disabled. When the function has been disabled, the doors will only lock by a door switch command or by pressing the the lock button on the RKE transmitter. When enabled, the doors will not lock until five seconds after the last door is closed.

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

Cant get my 99 xj8 out of valet mode, and my trunk will not open.


There are Valet keys (often with a green knob) that will
only unlock the front doors and the ignition but not the
glove box nor boot/trunk.

When either the front door locks or the console button is
pressed, all the doors should lock. Likewise, when either
front door is unlocked, all the doors fuel filler lid and if
selected, the boot will also unlock.

Boot lock has three positions. Unlocked to the left,
automatic with the doors in the center, always locked to the
right. Simply remove the key in what ever position you desire.

The locks can get confused and not work correctly. Simply
sit in the car and manually lock all the doors. That will
usually get the locking module sane again.

2005 Chevrolet Silverado Automatic door locks


I assume you mean that the central locking system will not lock the doors but you can do so manually.

Get inside the vehicle and close all doors.

On each rear door, lock and unlock the mechanism manually a couple of times. In other words do not use the key pad.

Then leave both rear doors in the locked position (manual locking) and operate the lock button on you key pad to operate the central locking system. Wait a few seconds then hit unlock on your key pad and a few seconds later hit lock on your key pad.

If the system fails to lock your rear doors you will need to get the vehicle to an auto electrician to check out the issue and rectify it for you. There are a number of possible causes which cannot be identified without physically checking the system. So you will need to have this rectified by a professional.

Automatic door locks will not lock rear doors, they open fine when manually locked but will not lock with switch key fob or when put in gear.

Program a remote key for 03 A6


I have an A4 and did this to re-program my key:

1. used the key to start the car...then turned it off
2. put the key in the driver door (door closed)
3. pressed the lock button on the key fob once
4. turned the key to lock the door.

This is basically the steps in the owners manual, but the car must be started with the key first, and the key must be in the door lock before pressing the lock button.
