Car chip keys, also known as transponder keys, are a type of automotive ignition keys that have a small electronic chip embedded in them. These keys are designed to prevent car theft by communicating with the car’s computer system and allowing it to start only when the correct key is inserted. In this article, we will explain how car chip keys work, how to tell if your car has one, how to get a replacement or a duplicate, and how to avoid common problems with car chip keys.
How Car Chip Keys Work
Car chip keys work by using radio frequency identification (RFID) technology. The chip inside the key has a unique code that matches the code stored in the car’s computer. When the key is turned in the ignition, the car sends a signal to the chip and verifies its code. If the code matches, the car’s immobilizer system is deactivated and the car can start. If the code does not match, the car’s immobilizer system remains active and the car cannot start.
The car chip key system is an effective anti-theft measure, as it makes it impossible to start the car by using a duplicate key, a hot-wire technique, or a bypass device. The only way to start the car is by using the original key or a programmed replacement.
How to Tell If Your Car Has a Car Chip Key
Most cars made after 1995 have car chip keys, but some older models may also have them. To tell if your car has a car chip key, you can look for some signs, such as:
- The key has a thick plastic head with a logo or a symbol on it
- The key has a small red or green light on it that flashes when the key is inserted
- The key is heavier and more expensive than a regular metal key
- The car has a security light on the dashboard that flashes when the key is inserted
You can also contact your car manufacturer, dealer, or locksmith to confirm if your car has a car chip key. At Cerrajero Metro Puerto Rico, we have the expertise and the equipment to identify and program car chip keys for most car models and brands.
How to Get a Replacement or a Duplicate Car Chip Key
If you lose or damage your car chip key, you will need to get a replacement or a duplicate. You have two options for this:
- You can go to your car dealer and order a new key. This option may be more expensive and time-consuming, as you may have to provide proof of ownership, wait for the key to be ordered and shipped, and pay for the programming and cutting fees.
- You can go to a local locksmith and get a new key. This option may be more convenient and cost-effective, as you can get the key faster, cheaper, and without hassle. A locksmith can also make a duplicate key for you if you want to have a spare.
