avital 4000

i got a avital 4000 remote start unit/keyless. It was a open box unit and did not have the rangemaster antenna. Where can i find an antenna that will work or another rangemaster? its a 3 pin white connector.

Also, its going on a 2000 sebring with sentry key, and factory alarm/keyless. Some say to splice the aftermarket keyless at the RKE module, others say its a 1 wire system, has anyone installed one using the original RKE wires?

Check out http://www.directed.com - they may have a replacement you can order. If not, then find a local dealer that sells any of their products - Viper, Valet, etc. all use the same antennas as that Avital. Also eBay might work.

There's absolutely no good way to interface the signals from a factory keyless remote to control any kind of aftermarket piece...however if I remember right that Avital has an input for a (+) trigger start - you can hook that to the doorlocks and set it up to remotely start the car.  You have to hook that to the lock motor lead, not the wire from the doorlock switch.

You still should get that antenna and remote - or at least borrow one while you're doing the install...none of the program settings can be changed without a remote.
