Tips to avoid locking your keys in the car:
1) Make a copy of your car key and placing it in a purse or wallet so you have less chance of locking the keys in your car.
2) Put your keys on a lanyard and put them over your neck.
3) Use a carabiner or clip so you can hook your keys to your belt, belt loop or purse.
4) Create an exit/lock routine- example: park, turn car off, put keys in purse, pocket, etc, get out of car, gathering belongings, and lock the car.
