Discovery Alarm!! keeps going off should i have a fob?

I have only had my discovery 300 tdi for about 3 weeks now, the gent who i bought it from said the alarm goes off now and again well this has got more frequent, i only have a key he didnt give me a fob now my previous 96 discovery 300 commercial had a key fob so should this one have one? if so where can i get a key fob programmed?

What model year is you disco if 1995 then NO, fobs were an option. 1996MY had a passive immobiliser therefor u need a fob to remobilise the engine, unless yours has had some DIY modifications.

The likes of Remotekey can supply a new fob and I believe now can loan u the programmer, just search their site.

well when i open the doors with the key its forever going off i looked on the alarm and its amr 2109 on the alarm ecu which according to what ive read if it does need one it would be a single button one?

From VIN MA 081992 the security control unit would be AMR2109, the fob for that unit is indeed a single button one (AMR3723 when new) which is 'user programmable' how to do that has been posted in the various Forums a few times.

If the micro switch with the drivers door isn't working fully when using the key and isola ting the alarm system the alarm will activate tea, have a look at the switches operating cam as they sometimes break, u will also find another micro switch that's for the immobiliser.

Well i have found a key fob on ebay finally, is it possible to programme the new key without the original key?

Yes, keyfob that is, not the key

haha done it all today and got it working no more alarm thanks discool for your help, now onto the next issue lmao

I have the same problem when unlocking car alarm goes off but not every time ,I have no key fob just a key .can I get a key fob for this as its a pain having to unlock drivers door before I can open another door or tailgate

what year is your motor? do u know what alarm it has?
