Hi, just purchased a 95 Brooklands and very happy, The central locking isn’t working, when I press the button on the door nothing happens. Am I right in thinking this is controlled by the alarm module and this could be the failed batteries in the module? Or could it be something else. I have checked the fuses. Thanks Andrew

I finally got around to this, dug out the alarm module and the batteries had leaked out onto the board. As batteries are cheap I tried replacing them but no luck, so I completely removed the alarm module, I studied the wiring diagram and installed a generic central locking unit, now the central locking works great, I also installed a kill switch.

You should have tried to keep the original one and have it repaired by a specialist such as Bowling Engineering.

I'm not sure about the 95, but the alarm module in my 98 Brooklands does a lot more than just the alarm. It has controls for the interior lighting and the immobilizer. I think that it's great that you were able to make a generic part work. You just replaced an unreliable unit that costs several hundred dollars to repair with a reliable unit that's likely never going to fail, and if it does, can be replaced with another generic unit for likely under $50. My only suggestion is to extend the wiring harness so that you don't to take the dash apart if you need to get to it.

Thank you
I studied the wiring harness very carefully, I have wired it so that the interior lights still come on when you unlock the car, I have also factored in the immobiliser so that it is still immobilised. I did try to extend the wires to have it down by the footwell but it wouldn't reach and I didn't want to extend the wires. I may add a windows up/down module with an internal switch so you can put all the windows down/up with 1 press and on the remote.

Thanks, if you're willing to share the pin outs. I'd be very interested in understanding this. My car came with no key fobs and the OMICHECK which is supposed to be able to program new fobs does not seem to be able to.

Best wishes
