my last post was deleted for link i guess

it looks like the AM DB7 uses the same keyfobs as our cars. the hard to find 433mhz fob is avaliable as part “37-84336”

 

Images I'm finding look more like the Saab style remote than the original Jaguar one. (Not saying it won't work. I have one of each, Saab & original, for my 315MHz car, but the Saab part lacks nice things like the brass loop.)

 

megamos made all these security units (and also the ID13 chip key). as far as i can tell 433mhz saab remotes exist but they were 315 only in the states.
