Aftermarket keyless entry remote installation 850 1996

Hi all,

I have a strange problem. I am fitting an aftermarket keyless entry system to my 1996 850. The central locking system itself is working fine, and I presumed that the installation would be an easy task. It was, except that I can't get the doors to lock! Unlocking works fine.

This is what I presumed:

The signal for unlocking doors is grounding pin 85A on relay - OK
The signal for locking doors is grounding pin 86 on relay - Doesn't work!

I have tried tapping into the lead to the relay and grounding it manually. Nothing happens.

The car has standard central locking, no deadlock.

Have I missed something?

Please drop a note if you have a clue to what's wrong.

Regards, Snorri H.
