I recently added keyless entry to my 91 Toyota MR2 using an Autoloc unit. The factory alarm system needs to see a double ground unlock pulse to deactivate the OEM alarm and unlock the doors. Unfortunately, the Autoloc will only send a single pulse, so I have to hit the remote button twice in a specific time interval for it to unlock the doors. Does anyone know how I can duplicate the double pulse action through relays, timers, etc., without too much complicated wiring? TIA

Todd

could use a timer relay, set it for like 1 sec and gets activated by the first unlock

Priority Door Lock Relay try using this but it still uses a 2 button press of the remote to activate the relays.
