When you lose your key, it is recommended to have a spare made. We have compiled a guide on the cost to replace a car key.
Mechanical Keys
It wasn't long ago that misplacing keys or losing it was not a big problem. You could purchase an extra and put it in the ignition. Today, however, cars are more technologically advanced, and it's much more expensive to replace keys lost.
An auto locksmith can be the cheapest alternative. They'll usually be capable of copying a basic metal key and do so for about $50 or less. This type of key does not have a chip, and therefore will not be able to unlock doors or start an engine.
Modern car keys have transponders, or chips, that must be programmed correctly. This is only done by a professional who is aware of what they're doing, such as the local locksmith or an expert from a dealership's service department.
The cost of mechanical keys is low, but the programming chip in the latest cars will typically cost you more than $300. It is best to always keep a spare key in your car and store it safely.
It's important to identify the type of car key you have before seeking help. A more traditional, older car key is a classic double-edged metal key that can be put into the ignition cylinder and then turned to start your vehicle. These aren't common anymore however you should be able to find them at your local hardware store for around $10.
The next type of car key is the transponder that has an embedded security chip that transmits a signal to the vehicle's computer system to unlock the doors and enable the engine to start. It is more difficult to duplicate than a mechanical key and can only be done with special tools, which are only accessible to a locksmith car dealer. The cost for this could be as high as $500 or more, depending on the make and model of your car.
Transponder Keys
Transponder keys are used by vehicles to communicate with their vehicle. They incorporate a microchip in the key. When the key is close to your vehicle or inserted into the ignition, it sends an electronic code which signals your car to start. This is a great feature to have as it deters theft. It also makes it difficult to steal your car because a burglar will need both the key and transmitter to turn it off and drive off with it.
The cost of a new transponder key is typically slightly more expensive than a conventional key, but this is due to the fact that it needs to be programmed as well. It is possible to program a key transponder by most locksmiths, but it is best to inquire with your car dealer if they can do it. This is because they typically have the most experience with these kinds of keys and could be able to offer you the most competitive price.
Many automakers have their own distinct anti-theft systems in place. It is important to do your research prior to purchasing your next vehicle. You will be able to figure out what type of key works with it and if it requires a remote to unlock it.
car key fob replacements come with a transponder-based password system. These are a bit more complicated because they require a particular key tool to program them. However they are more secure since they use rolling code encryption that changes the password each time they're used. This means that even if the key is cloned, it will not work with your vehicle.
It is crucial that you don't attempt to gain entry into your vehicle on your own, no matter the kind of key. This could raise red flags with insurance companies and could cause many mechanics to refuse to assist you in the event of signs that the vehicle has been damaged or opened. This can make it very hard to get replacement parts, so be certain to contact an professional Mesa mobile auto locksmith.
Laser-Cut Keys
A key that has been laser-cut is much more difficult to steal or lose than a traditional key. The keys don't have a notch along their edge. Instead, they have a groove that's cut to a certain depth in the middle of the face of the key. When looking at the key from above it's easy to tell whether it's a fake or not. The fact that they're so easy to recognize also means that you can avoid being locked out if you happen to misplace your keys while working or doing for errands.
If your key is laser-cut you'll need to call a locksmith that has specialized equipment for these kinds of replacements. Your local hardware store will not be able to make you a laser-cut replacement key, because they don't have the equipment to cut and program this type of key fob.
A locksmith uses an instrument that appears similar to a standard drill to cut the key's metal, which will cut off the entire surface of the key to the desired length. The key's unique code will then be retrieved from the VIN, and the key will be cut to match the specifications of your car.
Laser-cut keys are not like normal transponder keys because they don't contain electronic components or chips that can be changed. They must be destroyed and replaced with an entirely new model. Laser-cut keys can be extremely expensive due to the full rebuild of the key.
It's always a good idea to keep at least one spare key available in the event that you accidentally lose your car keys. Then, you can call a locksmith to have the key cut and programmed, so you can be back in your car without having to pay for it to be tow by the dealer.
Fobs
If you do not own a classic car, the chances that your car is equipped with one of the most advanced high-tech fobs that permit you to open and start the vehicle without the need for a key. These keys have special computer chips that must be programmed to fit your specific vehicle. There are locksmiths who can perform this reprogramming on your behalf but it's generally best to have your dealer handle it. They are familiar with the vehicle and have all the necessary tools.
The cost of having your car's key fob replaced could cost as high as $500, based on the kind of key you use and whether it's remote-controlled or smart. This doesn't include cost of a mechanical backup key that you might need in the event that the fob goes missing or is stolen.
The loss of your car keys was once a source of frustration. Now, it's a huge problem. This is because modern vehicles have made the keys so convenient and capable that thieves can now take keys, says Richard Reina, training director at CARiD. Fortunately, advances in car key technology have also made it harder for thieves to steal the keys.

The new keys are available in a variety of sizes and shapes, but the one that has both transponder and mechanical keys is the most expensive. This "smart key" has a spring-loaded shank that folds up into the fob, like the switchblade, making it less likely to get lost or tucked inside the pocket of a coat. These are usually more expensive than regular remote-controlled keys and could need to be replaced by a dealer.
If you have an additional fob that is compatible with your vehicle and that can be copied to work with another vehicle, you may want to consider ordering a replacement aftermarket from a company like Amazon or a specialist in key and lock who offers programming for many different vehicles. You may be able to cut and program your own fob for much less than a dealership charges, saving yourself up to $200 or more. Just make sure the new key and fob you purchase is the same year, make and model as the original to ensure it is programmed to work with your vehicle.
