I have a 2006 Highlander. It has keyless entry, but not the full RS3200 with security and transponder keys. Can anyone tell me if it is possible to reprogram this keyless enty to lock/unlock the doors when the car goes in/out of gear? My wife had this in her other car and misses it. I know the systemis tiedto the ignition, because the keyless quits working when the enine is running. Seems like a no-brainer to add the other feature, but 3 dealers have given me three different answers. Any help would be appreciated. Thanks.
