Hold your key FOB right next to the driver’s side door handle and try to open the door. The FOB might have just enough battery power left to unlock the door.

If the FOB has a leather jacket surrounding it, remove that leather jacket. Most manufacturers hide a very small key inside the FOB. IF you can expose the key, release the catch and pop out the spare key. Then use the key to open the driver’s side door. You can also use that small key to start the car, if necessary.
