1995 Toyota Camry Keyless Entry Help

I put in a keyless entry remote start on my dad's Camry.  The keyless was working fine uptil about a week ago.   Now the keyless doesn't work at all.  From the switch inside the car I can unlock the car that's about it, it won't lock at all.  That includes the switch on both front doors.  But it will still lock with the key from the outside. 

I tested the lock wire and there was no voltage at all, but the unlock wire still registering 12v. 

The unit is a Prostart CT-3300.

I also unplugged the lock/unlock wires and the switch still does nothing.  I also hooked up the unlock wire with diodes for the child safety wire.

I used a multi-meter to check for voltage.

That's what I have everything hooked up to.  The lights still flash but the doors won't lock or unlock.  Also the door lock switch does not work anymore either.  I think it's just the power door lock relay.
