[s-cars] 94 S4 infra-red key replacement options

[Christopher Leal]

S-heads,

Finally tired of replacing batteries and the crappy range I have with the infra-red key locking/unlocking. On a jeep I had I wired up a cheap aftermarket fob that gave me extended range. I noticed on Audiworld someone did this on their A4: http://www.audiworld.com/tech/elec52.shtml  Has anyone found better options for replacing the existing system? Maybe an upgrade to later Audi components with the RF capability?

Any guidance is appreciated.

Cheers,
Christopher
