ive recently bought my third mr2.

its a nice grey/blue 95 auto na
it has what looks like a toad alarm fob, but the central locking doesnt work, and neither does the fob.

relpaced the battery in the fob, but i have to use the immobiliser key inside the car to get it started as there is no central locking.

can anyone help with this issue?
cheers
luke
