Hello and thank you to anyone who reads this and may be able to point me in the right direction.
I have a late 1994 S500 ( UK car ) with the 1 button keyfob ( only one working ) which as it gets older, worries me more about future electrical headaches. I realise I should when I recommission the car again, which due to unreliability hasn't been used in 5 years, get another replacement remote key from MB, but have been thinking for a while it may not be such a bad thing for my personal circumstances to have the immobiliser and alarm system deactivated permanently.
I am quite content to have the car without the factory security system and know that I never need worry about the cars anti-theft system stopping me from starting it, which it did once before when the keyfob went flat and the alarm would sound when trying to turn the key in the ignition. I will of course have a replacement security system fitted.
The big question is I have heard of the system being deactivated, some say by the K38 relay having 2 pins connected ? Others have said cutting and joining harness wires ( does scare me a bit ) . Obviously many have had issues with this system, and I cannot justify spending a lot of money on a car which has already cost me a fortune with gremlins, and sadly isn't worth a lot of gold.
On the positive side the car is 100% rust free, lovely body and interior, but is just cursed with electrical issues . If the immobiliser should ever shut the car down on me, then off to the breakers she shall go sadly. Any positive guidance on how to deactivate this system permanently would be greatly appreciated.
