Keyless Entry

I have a 2001 S-10 with a aftermarket keyless, and it's been acting up. It's a TRC and one of my remotes will unlock it, the other will lock it. Also it only works on the driver side door, but if you in the car and unlock/lock the passenger side by hand it will unlock/lock both doors. It you do the same on the drivers side it only locks/unlocks the drivers door. Any help would be nice. :banghead:

This is obviously a problem with your aftermarket keyless entry system. I would start by checking any wire connections and any fuses. Might want to check your warranty also. It might be defective.
