Before We Get There
- Tell us the year, make and model, and whether you have any working key or fob.
- For a home: the address and which door.
- At a school or field, tell us which lot and the color of the car.

Good to Know
- I locked my keys in the car at school pickup. Can you help? Yes. Call us with the school and lot, and we'll come get you back in.
- Can you make a spare Hyundai key before I lose my only one? Yes. A spare is easier than starting from no key at all.
- Do you come to Catonsville at night? Yes. We're open 24 hours a day, all year.
- Both of our car keys are lost. Will you need anything from us? Just the car's details and proof it's yours, like the registration and your ID. The key is cut and set up right beside the car, and nothing gets towed.
- I came home and my key won't go into the lock. Am I locked out? Check that it's the right key first. If it is, something may be jammed inside the lock. Don't push harder; call us and we'll open the door and sort out the lock.
- Is this Baltimore County or Howard County? Baltimore County. The Patapsco River runs along the western and southern edge, and Howard County is on the far bank. We cover both sides.
