just bought a 93 on an L plate
have a key and "remote" fob and it seems to require random sequence and/or combination to operate door locks.
Anyone got the definitive method please ?????

Not sure that this is definitive, there's nothing in my handbook (which came with the car) about the security system and they changed, almost monthly at one stage and according to market, so almost anything you read in manuals etc tends to refer to a slightly different fit.
The car should lock, when doors and boot are shut, with one press of the button. If the button is pressed again within a few seconds, the lights should come on for a shortish (30 secs?) period. When coming back to the car it should unlock with one press of the button. If you lock the car with the key, the immobiliser doesn't arm, if you lock it with the remote, it does.
If you forget or the fob fails and you unlock the car with the key, the alarm will start to sound, softly at first and then gradually getting louder. There is a procedure for getting round this but I am not sure this should be published here. OK, I know the cars aren't worth much now but some are still attached to them.

puffdaddy,
Welcome to the Bulletin Board!
As Al correctly says, there are differing systems fitted around 93/94. I think that there are three different systems, fitted across the 1993 Model Year, 1993.5 Model Year, and 1994 Model Year cars.
The general principle of them all is the same. You press the button once to lock the car and and arm the alarm. The only thing that might be confusing you is that if you press the button again less than 3 seconds after locking, it won't unlock the car, it initiates the secondary sequences eg headlights on. Also, if you keep the button pressed down for more than five seconds, it might go into "panic" mode initiating an alarm, depending on which system is fitted.
So the simple process is, always leave a gap between trying to lock and unlock the car and don't keep the button pressed down.
The other problem might be that the mechanism inside the fob which allows the button to make contact with the circuit board, is prone to failure. The plastic mounting for the button can break and this might cause erratic contact when you press the button.
Hope that helps.
By the way, when you get a moment, can you please enter your car in the register. PLEASE ensure that you have all the relevant info to hand before you make the entry including VIN, engine no., paint and trim codes. If you have any problems finding the info, do please get in contact with me. Tks
