I have had a good look around the forums for assistance with this kind of problem and found one or two which unfortunately didn't help...

I bought my 1998 528i SE last night and one key works fine. However, the 2nd one will not open the car remotely.

The LED on this 2nd key flashes when you press a button, just as the other key does and I have tried replacing the key's battery and dismantled the key to check for connections etc and still no luck.

The key will open and lock the driver's door manually and start the engine but if the car is locked with the alarm set it has no effect when I try to unlock the main door/disable alarm using the remote butons on the key. I have tried locking/unlocking the boot remotely and also tried locking the car remotely but these do not work either.

Anyone have any ideas or does it just need the remote settings reset at a BMW dealer for that key? If so how much are they likely to sting me?

Any help would be appreciated as it is over 40 miles to my nearest BMW dealer!!

Try reprogramming the key,

1. Working from within the vehicle and with the doors shut

2. Turn ignition ON and back OFF within 5 seconds.

3. Remove the key from ignition and press and hold the unlock button for 15 seconds during this time press the key lock button 3 times within 5 seconds.

4. Release both buttons.

5. Doors will lock and unlock to show correct programming has occurred.

OK, I just went to the car using the first key and that doesn't work!

So this method re-programs each key by the look of it, so any ideas on how to program both keys the same?

Hi Mick :D

I had the same problem with my E46, as no one has posted a fix i'll show you how I got my 2 keys to work. Hopefully it'll work for your model???


Initialising key-chain transmitter
The key-chain transmitter is allocated to the general module in the vehicle by way of initialisation.

A maximum of 4 keys can be initialized for each vehicle.
The codes of all other keys are deleted when a key is re-initialized. This means that all the keys of a system must be initialized simultaneously.

Procedure
Carry out key transmitter initialization in the vehicle interior.

Unlock vehicle via central locking and close driver's and passenger's doors.

1) Briefly switch on terminal R in vehicle (maximum 5 seconds) and switch off again. => The system is now ready to be initialized.

2) Press and hold ”unlock” button on the key transmitter.

3) Point key transmitter in direction of antenna and, with the ”unlock” button pressed, press ”lock” button three times within 10 seconds (LOOKS LIKE ITS 15 SECONDS FOR YOUR MODEL MICK ).
=> A new code is generated in the key.

4) Release both buttons. => The general module signals that initialization of the key transmitter was successful by locking and unlocking the central locking system.

Repeat the procedure as of Point 3 (= press and hold ”unlock” button on key transmitter) to initialize the other keys. Terminal R must not be varied during this procedure.

DO NOT PUT SUBSEQUENT KEYS IN THE IGNITION

Good luck :thumbsup

PS I've just seen it is the same as Ronnies post, but you're following steps 1 to 5 to reprogram the 2nd key, you only need to do steps 3 to 5 for all subsequent keys.

OK Thanks for the fast reply SlowTech.
What do you mean by DO NOT PUT SUBSEQUENT KEYS IN THE IGNITION ??
I assume by this you mean just carry out the subsequent key programming/button presses all within this 15 seconds? You'd have to be fast to program 4 keys in 15 secs!
Does the central locking lock then unlock after each key is done??

OK guys thank you both very much for the help.
I now have both keys programmed and they work fine :D

The central locking does lock then unlock after each key is programmed and I got both done one after the other like you said without re-inserting the 2nd key into the ignition.

Easy-peasy when you know how!!

Thanks very much again :thumbsup

Hi, I have a E36 318IS Coupe and only have 1 key. It did work up until a few weeks ago but now it cant be used for the central locking so I'm assuming it's a dead battery which I plan to replace after a couple of questions.

Firstly, does the 318 E36 have a "terminal R"? And if so, where is it?

Secondly, my key fob has 2 buttons, red and grey. Would I be right in assuming red is for locking and grey is for unlocking?

And lastly, where abouts is the antenna situated as in point 3)?

Any help would be much appreciated,

Thanks, Mat.

Its not really my forte the E36 Matt, but here goes.....

Turn key in ignition to 2nd notch, when the dash lights come on.

Secondly, my key fob has 2 buttons, red and grey. Would I be right in assuming red is for locking and grey is for unlocking?
Dunno but sounds good to me:confused


And lastly, where abouts is the antenna situated as in point 3)?
On the E46 it is at the underside of the rear view mirror, so you could try holding the key up at head height directly above the handbrake.

If you don't sort it out I'd try a thread on the E36 Section of the forums, that's where the specialists are. :thumbsup

Thanks for a very prompt reply Slowtech.

Being new to BMW I'm clueless on pretty much everything!

As soon as I sort out why my dashboard lights aren't working I'll try this out.

Thanks again, Mat.

P.S Great forum by the way.

Thanks and some useful fob tips for idiots like me

Thank you Slowtech for the useful post - very helpful indeed. My first fob died about 3 months ago and today the second fob died on us. I thought it'd be an expensive £100 for a BMW replacement and that the batteries had given out.

Reprogrammed the fobs (2004 320 D ES) using your method and now have two fully working key fobs - greatly appreciated thank you.

A tip to any idiots like me - don't place your keys in your back pocket - think I keep wearing the batteries out by sitting on the buttons!!!!

Had to try a few times - think the timings may vary (i.e. key presses) for me it was something like...
  1. Key in ignition - to 3 setting (warm coils/ignition on) and back (immediately)
  2. Remove key...
  3. Hold unlock button and wait 7 seconds..
  4. Continue to hold the unlock button, but press the lock button three times slowly (a click is heard from dash area after second press)...
  5. Continue to hold unlock for a further 5 seconds...
  6. Release and doors lock/unlock.

(Repeat 3-6 for further keys.)

All working :)

Many Thanks again!

Am I correct in thinking the keys do not have a battery as such but a rechargable unit which is recharged when the key is in the ignition so it is wise to use both keys alternately say a month each.
