Problem solved!!!! YIPPEEEEEE !!!! I've finally done it. I tried again shorting out the 8 pins joining the receiver part of the module to the main body of the module, and this time it worked - it disarmed the alarm. Having done that I flicked the switch in the receiver, replaced it on the module, pr...

I'm still struggling with this because I can't disarm the alarm system in order to reprogram the remotes. I've read the informative post by Komis in the Boys Toys section and at least I now understand a lot more about how it works. If anybody thinks they can offer any advice please take a look at my...

Hi myredzed. Thanks for the photo. I've located the module and found the post you mentioned. I've followed the instructions to re-synch the remotes, but so far without success.

I've just charged the battery and started it for the first time in around 9 months. The central locking works fine with the keys but not with either of the remotes. I've fitted ...
