Outer Limits 4x4 Board

Hi all, just bought a new Navara D22, which has central locking, but not remote.
Is there an easy way/kit to hook up a remote, or do I need to go thru an aftermarket alarm place?
I have been quoted $275 for a driver door actuator and remote central locking to be fitted - any other options?

Thanks!

anyone??

has it got an alarm system?

you could kill 2 birds with one stone and fit an aftermarket alarm system.
