It's a 73 Vette and it has been parked for a long time.
I have a virtual switch setup in Hubitat that triggers a rule to unlock the door. The virtual switch is triggered by an automation setup in HomeKit.
I have this setup for both mine and my wife's phone and it works great. As an added safeguard I have another rule setup to auto lock the door after it has been unlocked for 10 minutes.
