Is it possible? Who makes a kit?

 

Ya, no problem. I had this done as my first mod. Go to Cartoys or whatever stereo shop that installs alarms and tell them what you want. They will need to add solenoids in the doors and hatch. I even got remote auto start and the antenna mounts above the rearveiw mirror out of sight. The remote is a pager also with a long range. My alarm is from Clifford. Stash a spare key under your car in case you get locked out.

 

Yep, just get any alarm system and it should come with keyless entry.
