I need to find out how to reset the Toyota central locking on my 1994 Celica. Toyota want to charge me $40. every time I get a flat battery. I would appreciate some help, thank you. Toyota Celica central...


Hi Georgia, try this

Before commencing, ensure all existing wireless door lock transmitters are
functioning correctly.
1. Locate the wireless door lock ECU. It is behind the centre
instrument panel.
2. Disconnect and remove the wireless door lock ECU from the vehicle.
3. Remove the four screws from the bottom of the wireless door lock
ECU, rotate and remove the top cover.

4. Remove the four screws from the bottom of the wireless door
lock transmitter and separate the top and bottom covers.
5. Remove the battery and note position for reassembly.

6. Locate the code ROM within the wireless door lock
transmitter.

7. Remove the code ROM from the wireless door lock transmitter
by carefully sliding back the retainer clip on the ROM socket.

8. Then slide the code ROM out of the ROM socket.

9. Locate the code ROM socket provided on the wireless door
lock ECU circuit board.

10. Slide back the retainer clip of the ROM socket.

11. Carefully insert the code ROM into the unclipped ROM socket,
ensuring the contacts are facing towards the circuit board.

12. Slide the retainer clip of the ROM socket forward to lock
the code ROM into position.
13. With the wireless door lock ECU top cover still removed, reconnect
the ECU to the wire harness taking extreme care not to allow any of the
internal circuitry or components to short out on any part of the vehicle.


14. Once in position, locate the reset button on the wireless
door lock ECU circuit board and press once only.

15. At the same time, confirm ROM coding was established by
observing the extension LED. This LED will flash once to acknowledge that
ROM coding was successful.
16. Carefully disconnect the wire harness from the wireless door lock
ECU and remove from the vehicle.

17. Remove the code ROM from the wireless door lock ECU and
refit into the wireless door lock transmitter's ROM socket.

18. Ensure the code ROM is secured and retained in the wireless
door lock transmitter's ROM socket.

19. Assemble the wireless door lock ECU and install into the
vehicle.
20. Assemble the wireless door lock transmitter. Ensure the battery is
installed with the correct polarity.
21. Check security system operation with all wireless door lock
transmitters.

Good luck

When, a key lock sing blinks on the dash of hummer H3, and will not start, what can i do ?


make sure all windows are closed
get out of the Hummer, using the central lock, lock the 4 doors
close the door
then open it with the KEY
then try to Start the Hummer.
(repeat several times till it works)
I am facing this problem now and that is the only soluttion I found. Untill i buy a new remote key that got stolen :S

In order not to fall in this problem, avoid opening the hummer with the key and directly locking the four doors using the central lock before starting it.

DRIVERS DOOR WILL NOT OPEN, WHEN OPENED FROM INSIDE WILL NOT CATC


I have this on a Passat 1998 model and it's frustrating, im at the point where all 4 doors wont unlock and the 2 front ones work with the key but need to be closed with the key again.The boot opens and closes with the remote.I removed and cleaned all four door barrels when they opened intermitently and under the passenger side footwell is the ecu for the windows&alarm which i removed and cleaned as well as soldered 2 dry joints.If i activate the fob i hear the relay in the ecu click and double click to lock and the boot lock works which indicates the electrics are ok.Doing a google there are 1000sssds of queries with passat/vw door lock problems and the main cause is dry solder joints in the door lock mechanisms in the door.I found out from the main dealer when replacing my bootlock(the old one was damaged in a theft attempt) that a new modified part was available and the same for door locks????leading me to believe this is a widespread problem.The only thing is to remove the door parts and inspect the catch and circut board for dry joints.This link may help you. http://forums.vwvortex.com/zerothread?id=1542461 copy and paste this into your browser or google the website if you dont know how.

Central locking and windows unusable due to leak


I've been dealing with similar problems (windows and sunroof dead, power locks iffy, dome light doesn't work, random chiming) and best I can figure is:

a) get rid of the leak and any standing water
b) depending on the year of your car check the relays and/or central locking module

I spent a lot of time checking the ECU and door interior parts and those were both dead ends. I also thought the standing water on the floor might be shorting actual wiring, but now I've eliminated that as well. Although my alarm hasn't been going off, the "door chime" has and the instrument cluster sometimes shows 3 or 4 doors open while driving. VAG-COM showed some alarm trip type faults as well. Central locking is my next move when I've got some time.

Central Locking not working


Hi Craig,
I'm running a E34 Tds Touring with a similar problem, my rear doors and tailgate have dropped of the central locking circuit.
I have been told it is the Central locking Module a large black box under the dash that is faulty, apparently a common problem.
Hope this points you in the right direction,
Please remember to rate my effort!

I don't know about the doors locking when the car is stationary, but many cars with central locking systems automatically lock when the car reaches a certain speed: normally somewhere between 10 and 15 mph.
