1993 850 alarm - how to disable? 850 1993

I picked up a '93 850 winter car, which has turned out to be a real peach. It is an 850 GLT sedan and I discovered it has an alarm system that is activated whenever I lock it up with the key or remote. A situation arose a couple weeks ago where I used the spare set of keys without the remote and locked the car up with the key. When I reopened the car, the alarm did not disengage and I was unable to start the car and as a result got standed. The owners manual indicates that the key should disable the alarm, but no matter what I did, this did not work. I had to have my wife drive to me with the remote with the other keyset and with the remote, lock and unlock the vehicle, disabling the alarm.

So my questions are, does anyone know what I am doing wrong or what is wrong with the vehicle? I am concerned that if my remote battery someday goes dead or the remote breaks, I may get stranded. I do not need the alarm, so if there is a way to switch it off, I am ok with that. Any and all advice is welcome. Thank you.

1993 850 alarm - how to disable? 850 1993

My 93 wouldn't start once after an unlock, plus the alarm red light red light stayed on. After 3 or 4 "on-off" cycles with the ignition it started. I had noticed an 850, same color, parked near by when I was parking . It was gone when I came back. The dealer told me the immobilizer had been activated, most likely caused by the wrong key used to unlock the car, suggesting the other owner tried their key in my lock by mistake. He told me the on-off trick with the correct key will re-set the alarm. Strange, and it never happened again in the 20 years I have owned it.

remove fuse number 6 and say goodbye to central locking ( fuel cap door is not locked without central locking, do it manually behind panel )

As Klaus advised.. you dont need the remote to activate and deactivate the alarm.

When i set off the alarm accidently i actually use the key and lock and unlock the car. It shuts off then.

I also find on my other car if i set it off.. i can first disarm it with the key and sometimes the little red light stays on. I guess this is meant to tell me that the alarm went off instead of getting the familiar blinking routine.

All i do is disconnect the battery if this happens for a few seconds and connect it again.
(just remember you radio code though)

Generally you should be able to use the key to do the disarming on the drivers door.

The next time you use "your" keys to lock the car, when you unlock it, unlock it twice. Ie., put the key in the door and turn it to unlock 2 times before opening the door.
