Remote car entry as remote trigger

Hello,

I want to build a remote bird launcher for hunting dog training so I need a transmitter and receiver with a remote trigger. I was wondering if anyone thinks I could use a remote keyless entry system as used for a car? Like the car door unlocker.. I'll be using a door lock solenoid as the mechanism to release the bird, so I thought what better to acutate the lock solenoid than a car door unlocker?

For this to work, I'd obviously have to have a more portable power source than a 12v car battery. So maybe 4 CR123A's would provide enough juice to power the receiver. I think I can work that out.

Mainly just wondering if I could use a system like the Avital 2101 as a remote trigger?

My other plan is to use my DX6i Transmitter and a dimension engineering battleswitch (and spektrum receiver) to power the door solenoid. However if I can get away with using one of the key fobs that would be better than carrying my DX6i around.

Other ideas?

Any help will be appreciated..

 

You can actually buy a system (Avital 2101 for instance - $30.50 at one site) that is just the fob and receiver. I just don't know if it can be tricked into being a stand alone system? All it would have hooked to it would be an external battery and one door lock actuator.
