Can a remote car key be replaced?
Yes, a remote car key can be replaced if it is lost, damaged, or no longer functioning. Replacing a remote car key typically involves contacting the car's manufacturer or an authorized dealer to obtain a new key and have it programmed to work with your vehicle.
Understanding Remote Car Keys
Remote car keys, also known as key fobs or keyless entry remotes, are electronic devices that allow you to unlock, lock, and sometimes start your car without physically inserting a key into the ignition. These keys use radio frequency (RF) or radio frequency identification (RFID) technology to communicate with your vehicle's onboard computer, enabling you to control various functions from a distance.
Reasons to Replace a Remote Car Key
- Lost or stolen key: If your remote car key is lost or stolen, you'll need to replace it to prevent unauthorized access to your vehicle.
- Damaged key: Over time, the remote car key can become damaged, making it difficult or impossible to use. This may be due to physical wear and tear, water damage, or other factors.
- Malfunctioning key: Sometimes, the internal components of the remote car key can fail, causing the key to stop working properly.
In any of these cases, you'll need to replace the remote car key to regain full control of your vehicle's functions.
Replacing a Remote Car Key
To replace a remote car key, you'll typically need to contact your car's manufacturer or an authorized dealer. They will be able to provide you with a new key and program it to work with your vehicle's onboard computer. This process may involve the following steps:
- Obtaining a new key: The manufacturer or dealer will provide you with a new remote car key, which may be a duplicate of your original key or a different model if your original is no longer available.
- Programming the new key: The new key will need to be programmed to communicate with your vehicle's onboard computer. This is typically done by the manufacturer or dealer using specialized equipment.
- Deactivating the old key: If your original key was lost or stolen, the manufacturer or dealer may also need to deactivate the old key to prevent unauthorized access to your vehicle.
The cost of replacing a remote car key can vary depending on the make and model of your vehicle, as well as the specific circumstances of your situation. It's generally a good idea to contact your car's manufacturer or an authorized dealer to get an accurate estimate and schedule the replacement process.

How do I get a new remote key for my car?
To get a new remote key for your car, you will need to provide proof of ownership (like the registration or title), a valid ID, and your car's VIN to a dealership, a locksmith, or a specialized auto key service. While a dealership can handle all types of keys, including high-tech smart fobs, a locksmith may be able to come to you and can be more affordable, especially for basic keys.
Step 1: Gather the necessary documents and information
- Vehicle Identification Number (VIN): This can be found on the dashboard or driver's side door jamb.
- Proof of ownership: This could be your vehicle title, registration, or a current insurance card with your name on it.
- Valid identification: A government-issued ID, such as a driver's license.
- Car make, model, and year: This is needed to determine the correct key type and programming requirements.

Step 2: Choose a replacement service
- Dealership: This is often the most straightforward option, especially for smart keys, but can be the most expensive. They have the correct parts and can perform all necessary programming. You may need to have the car towed if you've lost all keys.
- Locksmith: Many locksmiths can replace both basic and advanced keys. Some can come to your location, which may save you the cost of a tow. It is important to find a reputable locksmith who has experience with modern key systems, as some may not be equipped to handle complex programming.
- Specialized auto key services: Some hardware stores or online services can also cut and program keys, sometimes at a lower cost than a dealership. Be sure to check if they can handle your specific car's key type.

Step 3: Obtain and program your new key
- Once you provide your documents to the service provider, they will cut and/or program the new key for your car.
- For basic keys, this may be as simple as cutting the metal. For smart fobs or transponder keys, the new key will need to be programmed to work with your car's immobilizer and security systems.
- If you have two working keys, some cars allow you to program a third key yourself, which you can learn how to do from your owner's manual.
Can a new key fob be made from the VIN number?
Yes, you can order a key fob using your VIN, but you'll need to provide proof of ownership and likely have the vehicle present for programming. Dealerships and locksmiths use the VIN to look up your car's specific key code to create a new one, which can then be cut and programmed to match your vehicle's security system.
How to order a key fob by VIN
- Gather necessary documents: Collect your VIN, proof of ownership (like registration or title), and a government-issued ID.
- Contact a professional: Reach out to your car's dealership or a reputable automotive locksmith.
- Provide information: Give them your VIN and other required information to start the process.
- Program the new fob: The new key fob will need to be programmed to your car. This almost always requires the vehicle to be present to complete the process and ensure it's fully functional.
Why VIN is important
- Unique code: When a vehicle is manufactured, a unique key code is saved with its VIN, which allows for the creation of a new key.
- Security: Requiring the VIN along with proof of ownership is a security measure to prevent theft.
