Fob operated imobiliser/alarm removal

[Eratosthenes]

The key fob that came with my van around 8 years ago is looking quite fragile.
I have avoided using it on a daily basis as I think it is on its last legs.
What would be involved in isolating the alarm or would be an auto electricians job?

Generally on security grounds these things are placed in awkward corners, depending on just what sort of system you have then several circuits will have been cut into to prevent the engine starting and possibly also to flash lights etc. Unless you know what your doing and have experience its best left to auto electricians or get a an alarm installer to strip the old out and install a new modern system.

Thank you for your comments Geoff.

Is it not possible to obtain a (new) key fob.

Thank you for the reply.
I have searched previously to find one but was told that as it is a Japanese aftermarket immobilizer the UK ones work on a different frequency. I don't know enough about them to know if this is so. Do you think these may be available in UK?
What is worrying me is the van is having a service and MOT next week and as my other post the rear offside steel pipe has just developed a bad leak and if the battery has to be removed to gain access to replace the pipe I am concerned that when the battery is replaced and the fob is unable to stop the alarm and disarm the immobilizer.

You can often find both the cases and the electronics on eBay try a search there and if its just the case then it can be easily replaced.
Yes the original Japanese fobs do use a frequency that isn't ideal in the UK, however unless your frequently in range of marine installations where the military have/are present or in close proximity to TV satellite trucks then you shouldn't have too many problems .... however a few people have found that the military do have some un-disclosed facilities in other locations that can cause the occasional problem

I have just found a post on the forum about reprogramming a key fob. The actual key fob was actually sold on ebay a few years ago and is no longer offered for sale.
My fob has 4 buttons 2 for central locking and 2 for alarm/immobilser.
Would the programming for alarm/immobiliser be a separate procedure.
Any comments appreciated.
