2022 Tesla Model 3 Key Fob Programming Guide

Quick reference

Step-by-step on-board programming

Unlike many conventional vehicles, the 2022 Tesla Model 3 does not utilize a traditional key fob for remote entry and starting. Instead, it relies on a key card or your smartphone as the primary means of access. However, a Tesla key fob accessory is available for those who prefer a more traditional remote experience. Programming this accessory key fob is a straightforward process performed directly through the vehicle's touchscreen.

1. Access the Door Lock Settings: On your Tesla's touchscreen, tap "Controls" > "Locks."
2. Add a New Key: At the bottom left of the "Locks" screen, touch the "+" icon to add a new key.
3. Scan the Key Card: Follow the on-screen instructions and place your existing key card on the card reader behind the cupholders, or near the base of the front passenger-side door pillar (depending on your Model 3's configuration). This action authorizes the new key.
4. Place the New Fob: Once prompted, place the new key fob in the designated area. This is typically in the center console's cup holder area, or on the charge pad. The car will detect the new fob and pair it.
5. Confirmation: The touchscreen will display a message confirming that the new key fob has been successfully programmed.
6. Test the Fob: Test all functions of the new key fob (lock, unlock, front trunk, rear trunk) to ensure it is working correctly.

Battery replacement

The Tesla Model 3 key fob accessory uses a CR2032 coin cell battery. Replacing it is a simple process:

1. Remove the Cover: With the fob buttons facing down, use a small flat-head screwdriver or a fingernail to carefully pry open the bottom cover of the key fob. There's a small notch on the side for this purpose.
2. Remove Old Battery: Gently remove the old CR2032 battery.
3. Insert New Battery: Insert a new CR2032 battery with the positive (+) side facing up.
4. Replace Cover: Align the cover and press firmly until it snaps back into place.

Where to buy a replacement fob

Given the unique nature of Tesla's key system, options for replacement fobs differ from traditional vehicles.

• Tesla Service Center/Online Store: This is the most reliable and recommended source for a genuine Tesla key fob accessory. You can purchase them directly through the Tesla app, online store, or at a service center. Prices typically range from $150 to $200.

  • Pros: Guaranteed genuine, compatible, and comes with Tesla support.
  • Cons: Can be more expensive than aftermarket options (if they existed).

• Locksmith: While a locksmith specializing in traditional car keys may not be able to "program" a Tesla fob in the conventional sense, they can often assist with battery replacements or offer advice. However, purchasing a new Tesla fob through a locksmith is generally not an option, as they are proprietary to Tesla.

• Amazon/Online Retailers: Be very cautious when purchasing "Tesla key fobs" from third-party online retailers. Many listings may be for covers, cases, or non-functional replicas. Always verify the authenticity and compatibility before purchasing. If you are looking for an actual functional key fob, it is best to stick with Tesla directly.

If on-board programming isn't supported

For the 2022 Tesla Model 3, on-board programming is supported for the accessory key fob directly through the vehicle's touchscreen, making DIY programming straightforward. There is no traditional "immobilizer transponder" chip in the key fob that needs separate programming by a dealer or locksmith in the way a conventional car key would. The fob communicates wirelessly with the vehicle's system.

Since DIY programming is readily available, the costs associated with dealer or locksmith programming for this specific task are essentially zero, assuming you purchase the accessory key fob directly from Tesla. If you encounter any issues with programming or the fob itself, Tesla Service would be your point of contact.
