How to Replace a Lost Car Key
The loss of your car keys can be a huge hassle. Calling your local dealer or locksmith is usually the best way to start. They will require proof of ownership as well as the key from before in order to make a new one.
However, this is not always the cheapest method to take.
Traditional Keys
Traditional car keys made of steel were the first kind of car key. They have grooves on either side that fit into a matching set of slots inside the ignition. The key would then be inserted into the ignition cylinder and then turned to start the car. If you have lost a traditional key it is less expensive than other keys to replace them.
You can get a traditional key made by an automotive locksmith while you are waiting. The locksmith will require the model, make and year of your vehicle. The locksmith may also need proof of ownership in order to verify your right to purchase keys.
If you own a more recent vehicle, it's likely to have a transponder key. They cost more to replace but they are also more secure against theft. The plastic head of a transponder key has an electronic chip that communicates with the car's computer system to make sure that only the right key can be used to start the car.
The chips that are used in modern transponder keys are typically programmed with a specific code when the car is sold for the first time. Some of them employ "rolling codes" that transmit an individual code each time they are used, making it difficult for thieves to duplicate the key. It is recommended to keep your transponder keys in a secured location if you own an automobile equipped with one.
Transponder keys have a longer lifespan than traditional metal keys, but they are more expensive to replace should you lose them. You'll need to call your dealer to get an alternative transponder key in the event that you lose one. You'll need to provide your VIN, a 17-digit number that tells the dealer which vehicle it is compatible with.
You'll also have to provide the serial number of your car. This number is usually found on a label on the driver's side door, or a card in your owner's manual. These numbers are crucial because they can aid in locating your vehicle in the event that it is stolen or lost.
Transponder Keys
Your car key may have a transponder if your car was manufactured in the last 20 years. These tiny pieces of technology are programmed specifically for the specific vehicle, ensuring only you are able to start it. To make sure that the correct key is used to start your car, the transmission will lock if it detects that the code in your key does not match its code.
These keys are excellent for your car as they stop car theft. Traditionally, car thieves were able to simply touch two wires and use them to start your car in an operation called hot wiring. However, when cars began with transponder chips, it became much more difficult to steal them because the thief needs to have the correct key to send the signal required to start your vehicle.
Luckily, if you have traditional keys and lose it, a locksmith local to you can cut you a brand new one right away and erase the old one from your vehicle's system. On the other side, if you own a transponder or a fob key, then you will be required to visit the dealer to have it replaced. This is because the dealer will need to know your VIN (Vehicle Identification Number) in order to purchase the right key for your vehicle.
They must ensure that the key they purchase for you is compatible with your vehicle to be capable of starting it and open its doors. You will also need to show evidence of ownership such as your registration or title, in order to obtain a replacement key from the dealer. This kind of replacement might be a bit more expensive, but it's worth it when you consider the possibility that your vehicle key was stolen. If you are concerned about the cost of replacing your lost car key, check to see if it is covered under your warranty or car insurance. If not, you'll need to take your vehicle to the dealer to have it towed, and purchase the key from the manufacturer.
Fob Keys
The latest type of car keys are designed to act as remotes, allowing motorists to open the doors and start the engine without having to insert traditional keys into the ignition. These keys are also referred to as keyless entry keys or remote control keys and are typically less expensive to replace than older, more traditional varieties. But, like all pieces of consumer technology they're not a guarantee of durability. They're also easy to misplace and can stop working over time as they are moved around in your purse or pocket.
Fobs emit an electronic code that enables the driver to unlock and start the vehicle. When the fob is placed on a sensor in the car it reads the code and the doors will open and the engine is started. Some fobs have additional features, such as a button that calls the car (similar to the Tesla summon feature).
If lost keys lose your key fob, the initial thing to do is make sure that your keys are not in an unlocked purse or bag. If they're not there, go through your day and consider where you might have lost the keys. Check your pockets, in any bags you carried with you, and also on countertops or other surfaces. You may be able to find your keys in a place where you dropped them, or put them down briefly when you were attempting to buy something.
You can purchase replacement key fobs on the internet, but they have to be programmed to work with your particular vehicle. Certain key fobs, for instance those used by Audi or Subaru require to be programmed by a dealership. The good news is that roadside assistance organizations like AAA can often help in this regard, too.
If you do decide to purchase a new key fob, comparison shop. Some retailers will cut and program a fob that was purchased elsewhere at a lower cost than they charge to do the same thing at the dealer. It is also possible to replace only the outer shell of certain fobs with keys, leaving the electronics inside in working condition. Check your car insurance policy or auto club membership to determine if you have any insurance that covers this.
Chipped Keys
Cars have become more technologically advanced over time, which has lead to more sophisticated car keys. These newer keys cannot be duplicated by locksmiths. They require a special machine. It can be more expensive to replace the lost car key using chip.
If you lose your transponder chip key or it is stolen from you, you'll need to contact the local dealership to get a replacement. This is because they keep a record of the security information in their system and are able to pair an updated chip with your vehicle with no hassle. The process may take a few days, however, as the dealer will need to obtain the key from the manufacturer and it may take a bit of time to get it.
A professional locksmith can create an exact duplicate of your transponder key. It is a little more complicated than taking your car to a dealership however you'll save money in the end. You will need your vehicle's VIN number to get an additional copy. This number can be found on your insurance policy or on the sticker on the driver's side of the door jamb.
You'll need to bring a copy of the old key along. The locksmith will then match the key cuts. If you're unable to find the old key, then try looking in the trunk or other places where it might be hidden. You can also search your pockets and bags. You don't know if your set your keys down somewhere or if they fell out of your bag while reaching for something other.
