Depending on where you go for install, and also dependent on if your vehicle is a Manual or Auto transmission the install price will vary 150- 250. You will need a PATS bypass module 20 bucks, and need to have a second key programmed 50-100 bucks for your car if you dont have one, clutch bypass is necessary (even though its only a relay) 25 bucks, In the end, on a cold day, when you dont wanna run outside, its kinda nice, but also, as you may have read, if your battery aint up to par for WHATEVER reason, youll be an unhappy camper. I do have a remote start on mine, Im in Minnesota and it gets cold up here once in while, but be prepared for that ONE day out of the year, that your car may not start. my 2 pennies.
