Convert key with light to alarm / remote control

[Rs2-GTi]

I am tired of fumbling around for the keyhole once it gets dark outside, and I have been thinking of installing either an alarm or a remote control for the central locking system. But I really don't want another thing on my keyring. But I have the original key with the button and the light bulb, and I stared thinking maybe I could manage to fit a remote for the alarm or central locking inside that key. Have anyone tried to convert the key to an remote? My first thought - it's not very common for any remote to have one key for both opening og locking the car. Altso, the device needs to be able to be fittet inside the small key.

Have anyone done it? Remember I used to have an original alarm on my URS4 back in the days, can only remember the wierd bump on the B-pillar for the receiver, but not how the sender looked.

Is the answer not to change the barrels and the central locking motor to UrS6 stuff ?

This will give remote locking and unlocking on a key, which is much smaller than the newer style flip keys ?

Have a look at MDZ's project thread on his B4 Kingfisher saloon.

There are other threads on here which cover this issue.

Kind regards.

This the thread I had in mind.

My 94 German Spec UrS4 V8 avant had central locking via key only. I converted it to radio frequency remote using a RightClick kit from the UK. Hunter7 has since done the same thing.

You get a switch blade remote (actually 2 of them). And you can order the kit with the proper key blank. I like it so much, I plan to convert my infrared remote system on my 93 UrS4 sedan to RightClick.
