Lock and Unlock is controlled by the A19 connection.
Reasons why your door locks may be acting up can vary but here are some situations.
Wrong brown wire at the vehicles lock/unlock button. If you look at the connector at the wrong angle, you will grab a brown wire but it's the wrong one. (picture below)
If you're using datalink, no dotted line connections in the install diagram should be done. Also make sure that the Crimestopper is set to Fortin protocol in its options. Similarly, you can also try the setting the Crimestopper to ADS and changing the protocol in the EVO to AP/OFA.
Wrong Can wires at the OBD-II. Make sure they are the same color as listed in the diagram
Door trigger wires are reversed
