Hi jefgal,

Thank you for the donation and sorry for the delay in answering.

From the symptom descriptio, I would suggest checking the alarm control unit power supply and groundings.

Seems something is shorting causing the doors to lock and when ignition switch power is intermittently missing resulting in the alarm going off. Could be a faulty control unit.
