Hey, newb here with a quick tip if anyone is interested. Just finished a quick project to automatically lock/unlock doors with the ignition on older model LC's and LX's which do not have that programming feature available. I ordered a PAC-TR 7 off of ebay for around $25 (coincidentally, the same box can also bypass the alpine head units for video without using handbreak/e-brake inputs -- it is programmed different for this feature, though). Install can be done by anyone with some basic wiring skills. Five wires to connect: ground, power, trigger input (ignition) and two trigger outputs (lock/unlock). Let me know if you have any questions, as I did this install today and it works great!
