What to do when immobiliser touch pad stops working

the immobiliser is not stopping it from cranking but is stopping it from firing. run the fault codes as the immobiliser is not the only thing that controls the spark
it could be a flat battery in the key pad.

Please check owners manual for testing or resetting your key-less entry. Knowing the year and model will always save time. If you have time watch this youtube vid for 2016`s

you need to reset the alarm/immobiliser after replacing batteries,

Hello Abdul,
I had this problem and the solution is rather strange.... Change the battery in your remote key for a brand new fresh one and see if this solves the problem. Apparently, when the lithium battery is low, the central locking will continue to work but the immobiliser disarming circuit cannot decode the signal.

the circuit boards on those factory remotes, sometime break where the battery is clipped in, check to make sure the solder is holding the clip properly and it is not loose, also they remote may need to be programmed to the vehcile with a scan tool, usually only found at GM, Also the rubber part of the remote on the inside where the pad touchs the circuit board, uses a small screwdriver and touch the exposed circuit, if the remote locks the doors, try putting in tiny peice of alumumn tape of the inside pad, the connectiveness of the rubber wears off. If not try above or dealer.

will your passenger door open with the key and is it just one side that your windows are not working or both. if its just one side it might be your regulator motor in the door thats not working if its both it might be your central locking pump usually in the boot. however if both of them are working fine it could be that your key needs reprogrammed however i think the 1st 2 are more likely to be the problem.

car electrics are a nightmare. the car lights up when a door is open i presume. and by bypassing the central locking. the electric computer says there is a fault. and will not start. that i think is programed in. best thing to do is. go to phone VW dealer ask about diagnostic test without repair. about £35 then fix it yourself. they garentee it right I think. the dealers have come into line better with that kind of thing phone and ask anyway.

just unplug the immobiliser unit. its behind the glove compartment for rhd models.

try looking in the door and see if the bar to central door lock mechanism hasnt come off where the little plastic clip has broke that retains it

with any BMW they have their problems, one is the central locking/immobilizer, the central locking is linked into the immobilizer and vice versa, the immobilizer takes it signal to disarm from the central locking and the ignition key ring. (chip in the key) if one of these starts to play up it has loads of consequences this being one of them. they all need to work together for the system to work properly. you would need to read the alarm and immobiliser codes using an ob2 tool that can detect them, and find the fault some problems it can be the drivers door sensor in the lock this is the main door as its drivers side and it controls all other doors on the central locking. if the switch is worn in any of it movements the system will not know the door has been opened, this does not work on the interior light as that is a switch in the door frame. the door lock is lock unlock and deadlock with key with remote fob its also arm disarm alarm and immobiliser. i have seen in some models there is a sensor auto lock so when you walk away with the key the doors lock automatically all lease parts work together. any one having a problem can cause no signal to be sent to the others in the system to start engine .
