I chose to get a remote start from my local Lexus dealer and was willing to pay a premium so that I wouldn't have to deal with finger pointing if something went wrong. The system they installed, Audiovox AS-9055T does not provide the ability to open the locks by remote. I need to first kill the engine and then use the original RX remotes. I can neither open the doors or the back hatch after the car has been started remotely. This is cumbersome and my previous system (on another car) did not work this way. I had replacement remotes but they gave me full access to locking / unlocking the doors as well as opening the hatch. The dealer claims the need to kill the engine is necessary to not compromise the RX security system. I explained that I still needed to insert the key in the ignition before I could take the car out of park (the engine dies if the brake pedal is pressed without the key in the ignitiion as expected). I can also manually open the doors by using the key lock on the door handle. I've talked to many people with not only Lexus cars but Audi's, Volvo's, Infiniti's, and BMW's. None have to kill the engine before using the remotes to unlock the doors. I assume those vehcles have similr security systems. I also talked to several aftermarket installers and all say that they can install remote start without compromising the security system and allow for remote unlocking of the doors.
I suspect the dealer is giving me the usual mumbo jumbo but wanted to check with all of you before I have them remove the system and look elsewhere for a remote start.
Thanks,
