If I use the remote entry, it will provide a 500 milliamp momentary ground pulse. I would use it with a diode protected relay, the same as for the door and trunk locks.

I would test the solenoid for current draw. May need to boost the output of the remote entry system, either by transistor or another relay.

I think I'll go with a relay according to the "Weak Negative Output to Strong Ground Output" diagram....It will provide a degree of separation between the sensitive electronics of the remote entry and the larger current draw of the solenoid relay....
Thanks for your help, much appreciated.

If you do that diode your relay across the coil, 1N4004, band side to coil +.
