Quick answers

Can you make a car key if I have lost all of them?
Yes. Our techs cut and program replacement car keys on site in St. Louis, without a tow to the dealership. Bring photo ID and proof you own the vehicle and we handle the rest from the VIN.
How long does car key replacement take?
Most car key and fob jobs are finished in 20 to 45 minutes at your vehicle. Push to start and transponder keys take a little longer because the key has to be programmed to the car.
Do you program key fobs and remotes?
We program fobs, remotes and proximity keys for most makes and models, foreign and domestic. If your fob still works but the battery is dead, that is usually a much cheaper fix and we will tell you so.

If you have lost your car key, it’s imperative that you get it replaced as soon as possible. While standard keys don’t cost much to replace, transponder keys are more complex and contain a chip that communicates with the security system of your vehicle. The replacement of a transponder can be quite expensive, however, and costs from $50 to $110. Depending on the manufacturer of your vehicle, the cost of a basic key fob can be anything from $50 to $110.

If you have lost or stolen your car key, the best option is to call an auto locksmith. This is the fastest and most reliable way to replace a key, and it is not very expensive. In case your car’s ignition is changed, you should bring along the technical documentation to the locksmith, which will help him reprogram the keys. Depending on the complexity of your vehicle’s ignition system, a locksmith may need a couple of days to create a replacement key. If you’re in a hurry, you can also get another set of keys made for free.

In case your car has an immobilizer system, a locksmith will not be able to make a replacement key for you. Instead, they will need to program the new key to your car. A locksmith will be able to make you a new key right away if you bring the key to the dealership with you. This will cost more than a standard locksmith, but it is a more convenient option in most cases.

While car dealerships are a good choice, they are not specialist in locks and keys. Some dealerships use a specialist auto locksmith. In most cases, the dealership may not have the proper diagnostic equipment and will have to order key blanks. This will be the most expensive option, but it is still the fastest and most convenient. If you’re unsure which option is best for you, call a locksmith who offers emergency services.

If you’re looking to change the battery on your key fob, be sure to check the type of battery in the key fob. Most key fobs use a commonly available lithium battery. You can get a battery from a hardware store or larger pharmacy. If you’re unsure of the type of battery used, you can refer to your owner’s manual or look up videos on the internet to find out the exact type of battery that is needed for your key.

If you’re worried about the cost of a key fob, you can save money by buying one online. Then, just be sure to keep a spare set of keys in case you ever need them. If you’re selling your car, having extra key fobs can increase the value of your vehicle. The best thing to do is get a lock from a trusted dealer or professional locksmith. A reputable dealership will be able to help you with this.
