Lost or Stolen Keys
A key replacement can be costly and time-consuming. It is also possible to pay for a tow or to get your car's chip replaced.
One method to save money and time is to prevent losing your keys in the first place. Consider putting a brightly colored or reflective piece of your keychain or painting the bow of your key a hue that is noticeable. Keep a spare key on your seat in a safe place, just to be certain.
If you do locate your key lost, try to identify it by looking at the code that is stamped on the bow of the key. This information will allow you to determine if it's the correct key for your seat.
Transponder Chip Keys
Transponder keys, also known as key FOBs or chip keys (fobs which control your key), are one of the most common kinds of car keys. They've been around for over two decades and are designed to prevent theft by sending a coded message to your car whenever it's put in the ignition.
Transponders are actually microchip inside the plastic cover of your car key. When a key is inserted into a key FOB or the ignition of a car, it sends an extremely low-level radio signal (ECU) to the vehicle. The ECU detects a unique serial number on the chip, and responds in the same manner. If the signal is in line then the engine will start.
Transponder chips aren't completely secure, but they're an excellent way to decrease auto theft. The idea behind these types of car keys dates back to World War 2 military planes that used codes to differentiate them from aircrafts of the enemy.
If you're locked out and require a replacement key, a locksmith could easily make an additional transponder key to you. This is a little more complicated than simply rekeying a regular key, however, since the chip inside the new key must match up with the receiver in your car's system. This is the reason why obtaining duplicate keys from a dealership may be more costly.
Laser Cut Keys
Laser cut car keys are cut with grooves on both sides, in contrast to mechanically cut keys that can only be turned in one direction. They are more difficult to duplicate and are only used in the ignition or lock from either side. Also referred to as sidewinder keys are a step above the basic transponder keys/chip keys and offer more security in the event of a theft.
To make a Laser Key the locksmith has to recognize the cuts from the existing key fob to determine the type of blank to be used. Then, he or she must set up the key cutting machine to cut the key based on the original cuts. This requires a much more sophisticated key cutting machine than the traditional duplicators based on wheels that are sold in hardware stores.
seat car key fob programming are more expensive, but they are more secure for your car. Laser keys are not duplicated using the same equipment that make the standard edge-cut key. This stops the practice of "key-jumping," where a key for a vehicle is programmed to work with different vehicles and allows it to open the lock or start the engine. These keys must be recovered by a professional locksmith or dealer.
