Keys on the driver’s seat, a fob that died in a parking garage, or a trunk that latched with your keys inside: a car lockout always happens at the worst moment. Prime Locksmith Services is a family-owned mobile locksmith in St. Louis, and our technicians come to you with the tools to open your vehicle without scratching the paint, bending the door or breaking a window.
We open cars, trucks, vans and SUVs from every major maker, and we quote the price on the phone before anyone drives out. If your keys are lost rather than locked inside, we can cut and program a replacement on the spot, so you are not waiting on a tow to the dealer.
Whether you need car lockout service in St. Louis or help from an automotive key locksmith in St. Louis, one call to (314) 745-4590 gets a technician on the way.
















Most car lockouts are solved in one short visit. Here is how it works from the moment you call.
Give us your location, the year, make and model, and whether the keys are inside the car or lost.
We quote the job on the phone, so you know the cost before a technician heads your way.
Our technician checks your ID against the registration or insurance card. If those papers are inside, we check them right after the door opens.
An inflatable air wedge and a long-reach tool open the door without harming the lock, window seal or paint.
We make sure the locks and windows work normally, take payment and give you an itemized receipt.
The inside of a parked car heats up fast. If a child or an animal is trapped in the vehicle, call 911 before you call any locksmith, because police and fire crews can respond immediately. Once everyone is safe, we can take care of the lock, the key or any damage.
These are Prime Locksmith Services’ own price ranges, the same ones on our pricing page. Your exact price depends on the vehicle and the situation, and we confirm it before we start.

What moves the price: the vehicle’s age and security system, where it is parked, the time of day, and whether you also need a new key. Call (314) 745-4590 for an exact quote.
The classic lockout. We open the door and hand back your keys, usually without touching the lock itself.
If the trunk won’t open from the cabin, we unlock the trunk or truck tool box directly.
No key at all? We open the car and make a new one on site. Learn more about key fob programming.
A flat fob battery can leave a push-to-start car locked tight. We get you in and can replace or reprogram the fob.
When a key snaps off in the lock, we remove the piece and open the door. See broken key extraction.
A worn key or failing cylinder can lock you out with the key in hand. We open the car and diagnose the lock, or the ignition if that is the problem.
We ask every time. It protects you, and it is why a reputable locksmith never opens a car for someone who can’t show it is theirs.
