The metal tag is just your key number nothing more. You will need a functioning fob to remobilise the engine although the immobiliser only can be overridden by entering a code via the drivers door lock. The Code if you don't have it can be obtained from a main dealer, if they are helpfull they will look up your discos build data.
Info on entering the code is in the owners handbook.

Fobs can go faulty but first is the fobs battery is ok if you can't unlock/lock or remobilise the engine.

I suppose it's a tiping error and it's 97(not 87) disco

I dunno if that's what you're looking for but worth a look The Definitive Alarm Spider Post - LR4x4 - The Land Rover Forum

The alarm ECU send a signal to the CL master actuator in the drivers door to unlock if the there's a problem within the actuator then you have bounce back and the door will relock. Just a slight adjustment of the actuator on its fixing screws just a few mm eitherway and a bit of lubrication will should cure this.

Also if the small spring in the drivers lock is broken then the door pin will drop back down 1/2 way and relock, the door easy to check when unlocking with a key but beware this will set the alarm off.
