I *want* the keys to be locked inside my car

I think for you and your friend, you'll be able to do this...

1) They will need to leave the FOB inside the car but remove the physical key.
2) They will need to lock lock all doors and finally the drivers door using the physical key
3) You show up and you will need to either use the physical key to open the car or remote buttons. The proximity "unlock" should not work since there is a FOB inside the car.

Try to confirm that these steps work for you with your keys/FOBs.

 

So it sounds like you only have one key fob and one physical key?

If so, that sounds like your only option unless you can get an extra fob registered. You don't need to get the key made to save money.

 

Two fobs would be easier and I think that's the only way you could do this without having to wait for receiving a mailed key.

So yes, he would have to mail you back the physical key.

Try out the three steps when you get home to make sure everything works out. Good luck!

 

Doesn't the second FOB have a physical key also?!? Both of mine, do...

 

This is how you can do it.

1. Get a large piece of tin foil.
2. When your friend has parked the car, wrap the FOB with tin foil and leave it inside the car in the glove box.
3. Push the lock button inside the driver door.
4. Pull the door handle out while closing the door.

 

^ That sounds like it might work and defeat the inability to close the drivers door while keeping it in a locked state.

 

Another way to do it is:

1) Leave key fob in car
2) Roll down driver side window before powering down and getting out of car
3) Reach through open window and lock all doors from driver door
4) Hit Auto UP button on driver door and quickly remove arm

From what I remember on another post you have a short period of time after turning off the car to operate windows and lock doors.

 

Have your friend take the FOB battery out.
Leave it in the car.
Take the 2nd FOB with you and proceed as you would normally.
The FOB will work without the battery for ignition, but you must practically hold it on the start button.
They will be able to lock the doors because the proximity sensors will not pickup the FOB signal w/o battery.

 

On my car, if my wife leaves her key in the car. I just have to use the close button on my FOB. It opens the same way.

Try it.

 

2010 Prius 3rd gen: You can lock the key fob in the glove box if you wrap it in aluminum foil (and you get the other fob away from the car). Just lock the car with the interior lock button and close the door as normal. The other fob will unlock it as normal.

Curiously, I tried putting the fob inside a steel tool box instead of wrapping it in aluminum foil. No dice. The don't-lock-your-key-in-the-car logic played out, and it would not lock. Even if I put the toolbox in the back of the car. It appears that even minute leakage is enough to be received by the car. Yes, the box was steel -- I tested it with a magnet.
