Do it yourself project, then it's worth a shot. It's not exactly hard to do but just a lot of work. You need to take out your car panels, etc. If proffesionals can do it in 1 or 2 days, it may take you double the time at least.
The keyless starter is not too complicated for older model cars. For newer model, many cars need the car key to be in contact to start the car. So what happen is you need to hook up the autostarter system to a spare car key to fool the security system. So a spare key is required to be placed inside the car (have to hide it ofcourse).
Many stores offer 0 or 1 dollar installation now. They are not exactly free. They will sell the components / system at higher price but in my opinion, it's totally worthed. You know for sure your system is installed correctly and they usually guarantee their installation for a year at least.
I tried doing it myself before. I gave up half way. It's not because I couldn't hook them up, but because I didn't realize earlier on how bad I needed to strip the car. If I continued myself, I might have the car sitting in my garage for over a week (I couldn't work on it full time also). I'd rather have a pro to continue it and get it done in a day. Since I bought the components myself, I had to pay all the labor and parts for the installations. After I calculated it, the more expensive prices those $0 installation stores charge are actually not a bad deal at all.
I've got a 97 nissan sentra gxe with power door locks and etc.
I wanted to install a cd reciever, speaker set with keyless entry and remote start. I keep coming across these keyless entry +remote start DYI packs in stores, but is it that simple to install? Or how much work would be involved.
Also in general, how much does it cost to fit one of those systems in the US.
Any insight would be appreciated.
