It can be frustrating when you need a spare key for your FJ Cruiser and are faced with potentially high dealership costs. Many FJ Cruiser owners find themselves in similar situations, often with only one original key. The good news is that getting a replacement or spare key fob for your FJ Cruiser doesn’t have to break the bank. This guide will walk you through a cost-effective DIY approach to Fj Cruiser Key Fob Replacement.
To begin, understanding the type of key your FJ Cruiser uses is crucial. These keys are typically transponder or chip keys, requiring specific codes for both the key and the remote functions. For the transponder key, you’ll need a four-letter code. A common code for models around 2008, for example, is 4D67. You can usually find keys compatible with your FJ Cruiser year by searching online marketplaces like eBay for “replacement keys” and your specific model year.
The remote function of your key fob is identified by an FCC ID, an 8-character code. This code might be stamped on your original remote. If not readily visible, an online search for your FJ Cruiser year and “FCC ID for key fob” should provide the correct code. A frequently used FCC ID is HYQ12BAN. When ordering a replacement, whether it’s just the remote, just the key, or a combined key fob, ensure these codes match your vehicle’s requirements.
Once you have your replacement key and/or fob, programming them is surprisingly straightforward and requires no specialized tools. Online videos and instructions detail the process. For key programming, you’ll generally need your existing working key, the new blank key, and the correct programming sequence. Similarly, programming the fob requires a working key and the new fob. While the programming steps might seem unusual, often involving cycles of door opening and closing, they are effective.
After successfully programming the transponder and remote functions yourself, the last step is getting the physical key cut. Many owners have found that hardware stores like Home Depot will cut the key for free, especially if you bring in your own blank. They usually only charge if you purchase the blank key from them.
By sourcing a key and remote online, like from eBay for around $15, programming it yourself at no cost, and getting the key cut for free, the total expense for an FJ Cruiser key fob replacement can be minimal. Consider exploring options like folding keys for added convenience. Even if a folding key is originally designed for another vehicle, as long as the key and fob codes are compatible, it can work perfectly with your FJ Cruiser.
For those preferring alternatives to eBay, websites such as remotesremotes.com are reputable sources for replacement key fobs and remotes.
In conclusion, replacing your FJ Cruiser key fob can be an easy and inexpensive DIY project. By identifying the correct transponder key code and FCC ID, sourcing a replacement online, programming it yourself, and finding a free key cutting service, you can save significantly compared to dealership prices. This approach ensures you have a spare key without unnecessary expense or hassle.
