BMW X3 Key Programming
BMW X3 Key Programming
BMW X3 - Key Remote Programming
Three methods to try:
Method 1:
1. Working from within the vehicle and with the doors shut
2. Turn ignition to position 1 and back to 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.
Method 2:
To do this procedure you need to have one working key and one key that needs to be programmed.
1) Get in and close all doors.
2) Turn on the ignition and turn off quickly. (No more than 5 seconds) to start the process. Next action must take place within 30 seconds.
3) Remove the 1st key.
4) Hold the key up near your left shoulder (this is so it is closer to the remote receiver antenna.
5) Hold down the unlock button and press the lock button 3 times. Release the unlock button and the doors lock which confirms the operation.
6) Quickly repeat steps 4 & 5 for key #2 etc.
If it does not work, try doing the keys in opposite order. Key 2 then key 1, vs 1 then 2.
Method 3:
Alternate if you do not have a working remote
1. Turn key to position 1 five times very quickly 2. Remove key 3. Hold unlock button then press lock button 3 times, release unlock button.
4. If you have another key do the same button pressing within 30 seconds 5. Turn on ignition to finalise.
PLEASE NOTE: This programming procedure programs the remote control part of the key. Any transponder chip for the immobiliser (starting of car) will not be programmed and must be done by a specialist.
Thanks Rabs for that , but I also need it to start the car . So it will be off to the stealership then
does sound that way ill have a bit more of hunt though as it may be possible to do it im assuming u have a new key that's not programmed rather than an old key that's lost its programming ?
You presume correct Rabs , I only have one key for the X3 and one I bought from ebay to get re cut and re programmed
from another quick look it might be worth trying that as some sites clasify this as a transponder programming if this is the case then your car should start after all if the car receives the signal to unlock from an authorised source its halfway there to start lol
give it a go 1 of 2 things will happen
it will work and save you a trip to the stealerships
it wont work and you will have to go to the stealerships
Or it wont work and the first key will stop working , then I get a kicking from Mrs Moley
hmmm you have a point but i cant see it corrupting the key you have
from reading it a few times and the same info on a few site it shows that option 3 is the only one that doesn't do the immobiliser programming which makes sense as its for those that have no key thus a car thief etc...
the 1st 2 takes note you have a key that's programmed..... this has no mention of not programming the transponder a bit like the is200
if you have no working keys you have to get a new ecu etc to have keys that work....
other thing is call up the dealerships to enquire about key programming cos if its over the £400 mark you may as well get an after-market cat1 alarm fitted then the 1 transponder you have got can be mimicked by this to allow the car to start and you just have standard blade keys for the rest of it plus the alarms come with 2 fobs and further fobs are under £50 and easy to program.....
