I want to install a remote start on my Jeep Liberty and was wondering if you have any recommendations. My son will install it but I would prefer something that isn't too complicated.

There's not really any such thing...remote starts are probably the most complicated accessory to install on a car. I would recommend perhaps a DesignTech or Boa, since they offer tech support for the DIYer and have reasonably well written instruction manuals.

Details on the car itself:

1. The parking lights and power locks are multiplexed, meaning that if you connect to them you'll have to use relays and resistors, which isn't too much fun at first.

2. If your key has a gray head, the car has the SentryKey immobilizer system(black head keys don't have this), which requires a bypass module, also sold separately from the remote start.

Sorry about the previous reply i pasted from worr and the post went crazy.

Unless your son is a certified installer i would encourage you to have the remote starter installed by a professional, messing up wires on that truck could result in one hell of mechanic's bill. Chriswallace187 is right, there is lots of multiplexing on Jeeps/ Chrystler/ Dodge vehicles which is difficult to interface with using analog wiring (resistors, diodes and relays). With out proper instruction and having the specific resistance values at your disposal its an extremely difficult task. Chriswallace187 also mentioned the coded grey key, which is also a huge obstacle for the new installer, the bypassing procedure requires you having both keys and either leaving one in the bypass module or programming the bypass as another key using the OEM programming mode (this depends on the model of bypass you have). I would recommend that your son try installing on a less difficult vehicle before he attempts the liberty. I am in no way speaking poorly of your son's skills i am purely commenting on your vehicle of choice. All of my installers, and even I myself, took upwards of ten hours to learn to work propperly on these vehicles and this is after months of training both theory and hands on
