The hardest part of the install (of a trimark system) is getting the lock actuator installed in the door. After that it is just routing wires, and mounting. But opening (cutting) a hole in the side of your door (for the actuator) is not for the faint of heart. Trimark has all he parts to install this. I think I spend like $250 for all the parts.
