It's a Disco 300TDi and has central locking but I was wondering if it would originally have had a remote key fob as it didn't come with? It does have electric windows if that helps.

depends on the year and model ie, es ,xs ,or bog standard. If its 94 onwards it should have it fitted, phone yourlocal dealership with your vin plate numba and they can check for you,an may be able to order a new one for you. good luck hope this helps, Dave 300 tdi es proud owner.
