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

[Theodore Chen]

looks nice, and not much more expensive than the one i used.  i would contact the seller to ask for a copy of the installation manual.  you're looking for confirmation that it grounds the outputs to activate (lock), and double pulses to deactivate (unlock).

i didn't like the factory IR system.  the range was so limited that i had to stand next to the car to use the remote, and then i might as well as use the key.

Any thoughts on this system that comes with "switch blade key" remotes?

Ebay auction #120331094209 or link below.

I'm tempted to replace my bulky IR remote with this system!
