Is this possible to do..I have manual door locks
but i want to install a keyless remote/starter.
Do-able ?

yes, it's doable. you need to install actuators and connect them to the manual door lock system. the actuators are controlled by a keyless remote/starter module. if you're getting a keyless alarm/starter installed by a professional, they should be able to do it for you.

Good deal ..Thanks for the info =]
