2020 Tesla Model X Key Fob Programming Guide

Quick reference

Step-by-step on-board programming

Good news! Programming a new key fob for your 2020 Tesla Model X is a straightforward process you can perform yourself, right in your vehicle. No special tools or trips to the dealership are required.

1. Enter your Tesla. Make sure all doors are closed.
2. Locate the card reader. This is typically found behind the cup holders in the center console.
3. Place your existing, already-paired key card or key fob on the card reader.
4. On the touchscreen, tap Controls > Locks > Keys.
5. Tap the + icon to add a new key.
6. Place the new, un-paired key fob on the card reader. The touchscreen will prompt you when it's recognized.
7. You may be asked to enter a PIN to confirm the pairing. Enter your chosen PIN.
8. Once the process is complete, the touchscreen will confirm that the new key fob has been successfully paired.
9. Test the new key fob to ensure it locks, unlocks, and opens your vehicle's doors and frunk/trunk.

Battery replacement

Replacing the battery in your 2020 Tesla Model X key fob is a simple DIY task.

1. Remove the bottom cover. With the Tesla "T" logo facing up, gently push the bottom cover of the key fob towards the top. It should slide off with minimal effort. You might find a small indentation on the side where you can apply a little pressure to help it slide.
2. Remove the old battery. The battery, a CR2032 coin cell, will be visible. Use a small, non-metallic tool (like a plastic pry tool or your fingernail) to carefully pry the old battery out of its holder.
3. Insert the new battery. Place the new CR2032 battery into the holder with the positive (+) side facing up.
4. Replace the cover. Slide the bottom cover back onto the key fob until it clicks securely into place.

Where to buy a replacement fob

When it comes to replacing your Tesla Model X key fob, your options are a bit more limited than with traditional car manufacturers, primarily due to Tesla's proprietary technology.

• Tesla Service Center/Dealership: This is the most common and often the only direct route for a new OEM key fob. While convenient, it's typically the most expensive option, often costing $150 - $250 or more for the fob itself, plus any potential labor charges if you opt for them to pair it (though, as shown, you can do it yourself). The advantage is guaranteed compatibility and warranty.
• Aftermarket Retailers (Amazon, eBay, etc.): You'll find fewer "aftermarket" options for Tesla key fobs that are truly equivalent to the OEM. Most listings might be for replacement shells or used OEM fobs. If buying a used OEM fob, ensure it's truly "unlocked" or "virgin" and can be paired to your vehicle. Beware of extremely cheap options, as they are likely not genuine or functional for programming. Prices can vary widely, but expect to pay at least $100-$200 for a potentially working used OEM fob. Exercise caution and verify seller reputation.
• Locksmiths: While an automotive locksmith can certainly assist with many key programming needs for other vehicles, for a Tesla Model X, their capabilities are generally limited to cutting traditional key blades (which the Model X key fob doesn't require) or battery replacement. They typically do not have the necessary equipment or access to Tesla's proprietary software to program a new key fob. However, a locksmith might be a good resource if you need help disassembling the fob for battery replacement or troubleshooting.

If on-board programming isn't supported

Fortunately, for the 2020 Tesla Model X, on-board programming is supported, as detailed in the steps above. You won't need to visit a dealership or locksmith specifically for programming.

Tesla Model X key fobs do not use a traditional transponder chip in the way many other vehicles do, nor do they require a physical key blade to be cut. The security system relies on encrypted communication between the key fob (or key card) and the vehicle.

Should you encounter an issue where the on-board programming doesn't work, it's almost always a problem with the key fob itself (e.g., faulty or not "virgin") or a rare vehicle software glitch. In such cases, your only recourse would be a Tesla Service Center. The cost would likely be the price of a new key fob, as mentioned above, and they would perform the programming at no additional charge if you purchase the fob from them.
