Installed Compustar alarm to 2017 Express Van and customer wants factory locks to work normally with switch and alarm but side door and rear door to not unlock either way.
I cut motor unlock wire but lock also stops working.
Is there a solution for this.Thanks in advance.

Do both wires of the motor rest at ground? If so, the following will work.

Put a relay on the unlock wire. The wire that you cut, 30 to motor. 87a to the wire that goes to the vehicle. 87 and 86 to 12 volts. 85 to the unlock wire of the alarm/keyless unit. During lock, the motor will still be connected
