keyless entry possible?

jus bought 2010 tacoma basic model, has power door locks but no keyless entry remote or system yet. can i get a plug in module from toyota to complete system or after market thats not so complicated in hooking up so many wires?

 

Just get one of these or similar. Install is not as difficult as a full on alarm or remote starter. IIRC you need to make switched and unswitched power connections and siamese onto the lock and unlock wires in the kick panel. This unit will also do optional parking light flash and dome light supervision that requires additional connections.
