OIC, yes you do have a problem with the key if you can open the door with the unlock button at the gear console.

This applied for key that is diamond shape.

Maybe you can try this procedure to resyn your key. Thanks affan66 for the link.

Initialization Procedure.

1. Open central locking system using the car key.
2. Get into the car and close all doors.
3. Using the car key, switch the ignition lock briefly to position "1" and then switch off again. (Please do this switching within 5 seconds or otherwise the system is not ready for initialization.
4. At the remote control key. Press the "OPEN" key (->) and keep holding.
5. When holding the "OPEN" key, press the "LOCK" button three time.
6. After pressing the "LOCK" button 3 times, release the "OPEN" button.
7. If the initialization process is sucessful, the door will lock and unlock immediately to confirm the process.

Please try whether it works.

er, how to try this with the non-diamond type key??

Bro,

I also have this problem sometime with my remote. Click the remote, alarm sounds but the door does not lock / unlock. Have to press unlock / lock again before can lock / unlock with the alarm sound.

But my remote is the old one, not the diamond shape one. So how, got any advice?

Thanks

The diamond key is recharge when you plug it in the key slot. As your is the older version, I presummed that it is the squarish type, then your battery is old and voltage is low. Pls change the battery first and see how it goes. When the battery voltage is low, the correct signal to trigger the alarm is weak and hence your alarm will sometime work.

The older version door lock module is GM4. I dont think it have the resyn feature as the GM5 version.

My problem is definitely the key, as one works fine and the other doesnt. Mechanic is tearing apart my diamond shaped fob, look for the battery and code...apparently mati liao. Cannot recharge.

yo.. I am also still figuring how does the battery get charge when you insert it into the key slot.

Normally battery is charged by "+" and "-".. Apparently the key is only one contact point.

When your mech open the key, did you take picture? Would like to see the inside of the key. Dare not open mine cos still working..

Lucky that you are in the same line and know about electronics. If it was me, I would have to get a new ZKE module....:sleep:

Same goes here.. I know nut about accounting and finance.. :stupid:

Everybody have their own interest but I do know some people who DIY not because of cost but to know their car better.. :wink:

Sometimes, there is no need to buy a new ZKE if it can repair with the help of the forummers advise. Afterall this is what the club is all about.. share.. share mah..

bro, no problem.. It good to share good information.. In fact, I think that web site is one of the most helpful site that I find that help me find out the problem with the E46 central locking.. :listen:

So how is going your with your ride? Any weird experience with the central locking with your ride.

 

[kskee]

yup....agreed..... a wealth of info on the web.... and thank God for forums like this....hehe

I'm driving a 1996 e39 528i ..... recently having intermittent problems with the central locking and power windows .... think mine is related to the General Module as well ....

still can't believe that BMW soldered the relays on the circuit board....damn .... I used to change the relays on my own for my earlier cars without any hassles.... if only my soldering 'kung fu' was good enough to try removing the relays from the circuit board....LOL

still looking for options on what I can do.... cos it seems to be working normally more often than not. ..... but dunno how long before i start climbing up the wall....LOL

Since the weekend I have been facing a similar problem with the locks too! I can lock/unlock the doors manually but not with the key-remote system. Initially I thought the batteries died on me again and had them replaced. Bought 2 brand new Maxell 2016 batteris and still it doesn't work! I am still on manually mode.

Anyone has face this before? Any solutions/recommendations? Please advice.

Cheers.

3 doors and 3 different type of problems.. I think the problems occurred over a span of several months.

You are lucky that the 4th door did not jam or else you will be admiring the car and not drive it.. :wink:
