In recent years, many online marketplaces have emerged that specialise in car keys, offering a more affordable alternative to buying a new key directly from a dealer, which can often be prohibitively expensive. Depending on the make and model of the vehicle, aftermarket keys can sometimes be pre-programmed with aftermarket firmware that matches the frequency of the original remote and comes equipped with a blank transponder chip ready for programming. While these keys may seem like a great deal, it's essential to consider the additional costs involved in getting the key programmed after it arrives in the mail.
Key Cutting
One of the first steps after receiving your key is to have it cut. Although it may be tempting to reuse the blade from an old, damaged key (especially on flip keys) this is not advisable. The wear and tear on the old blade can eventually damage your vehicle's locks and ignition, leading to costly repairs and potentially leaving you stranded on the side of the road. As an experienced locksmith, let me tell you, ignitions rarely jamb up while your at home! Instead, it's crucial to have a locksmith cut the key "back to code." This means cutting the key to the manufacturer's original specifications. Locksmiths can use the code assigned to your vehicle's locks to create a pristine key that look like it has just come off the factory floor and functions as well as the original. Some key cutting kiosks and locksmiths who don't specialise in automotive locksmithing will sometimes cut a new key by tracing the original. This replicates the existing wear and damage, which is why a professional locksmith using a CNC style key cutting maching is always recommended.
Transponder Programming
The transponder chip in your aftermarket key will need to be matched to your vehicle’s immobilizer system before it can start the car. There are a few methods to achieve this, with diagnostic programming being one of the
most reliable. A locksmith can use a high-quality scan tool to connect to your vehicle’s computer system and program the new chip to work with the immobilizer. However, be cautious of low-quality scan tools, often used by unregistered locksmiths found on social media marketplaces. These tools can corrupt your vehicle’s data, making it undrivable and requiring expensive repairs. When you choose a professional locksmith, they will use reputable tools to ensure the programming process is safe and effective.
If the key you purchased is a replacement for a damaged key with an intact transponder, you might be able to transfer the existing chip to the new key, leaving only the remote to program. In cases where the transponder chip is not compatible, it may be possible to clone the existing chip onto a new one. Cloning is often a more affordable option compared to diagnostic programming.
Remote Programming
Programming the remote to communicate with your car is another critical step. In older vehicles, remotes can sometimes be programmed using a manual procedure known as a "chicken dance." This involves a specific sequence of actions, such as opening a door and turning the key in the ignition, all performed with precise timing. While this can be done at home with little risk, newer vehicles often require diagnostic tools to program the remote. Your online key dealer should inform you whether diagnostic programming is necessary.
