2025 Tesla Model Y Key Fob Programming

Quick reference

Step-by-step on-board programming

The 2025 Tesla Model Y utilizes a key card or your smartphone as the primary key. The key fob is an optional accessory and is programmed directly through the vehicle's touchscreen.

1. On the touchscreen, touch Controls > Locks > +.
2. Scan your new key fob or key card on the card reader behind the cup holders or on the wireless phone charger.
3. Ensure your key fob functions correctly by locking and unlocking the vehicle.

Battery replacement

1. Place the key fob (button side down) on a soft surface and use a small flat-bladed tool or fingernail to release the bottom cover.
2. Remove the battery by carefully prying it away from the clips.
3. Insert the new CR2032 battery with the '+' side facing up.
4. Align the bottom cover with the fob and snap it back into place.

Where to buy a replacement fob

• Tesla Service Center: You can purchase an official Tesla key fob directly from a Tesla service center or through their online shop. Prices typically range from $175-$250 for the fob itself. Programming is easily done through your vehicle's touchscreen.
• Aftermarket Retailers (e.g., Amazon, E-Bay): While aftermarket options may emerge, always exercise caution when purchasing non-OEM key fobs for a Tesla. Ensure the seller is reputable and the product is explicitly stated to be compatible with model year 2025. Verify its functionality upon arrival, as returns can be complicated. Due to the advanced nature of Tesla's security, cheaper generic fobs are unlikely to work. Prices can vary widely, but expect to pay less than a Tesla-branded fob, potentially in the $75-$150 range if reliable options become available.
• Locksmiths: A locksmith can certainly assist with key fob issues if you're having trouble, but for a Tesla, especially for programming a new fob, they will likely direct you to use the vehicle's on-board programming feature or suggest purchasing directly from Tesla. The primary advantage of a locksmith for other vehicles (cutting mechanical keys, advanced programming tools) is less applicable here. They can, however, replace batteries and help troubleshoot basic connectivity issues.

If on-board programming isn't supported

Good news! For the 2025 Tesla Model Y, on-board programming is supported directly through your vehicle's touchscreen, making adding new fobs a straightforward process. There's no need for specialized scan tools or dealer visits for this task, which saves you both time and money.

Since the Model Y primarily uses key cards and phone-as-key technology, the fob is an accessory and does not contain a traditional immobilizer transponder chip in the same way older vehicle keys do. The vehicle's advanced security system handles authentication. Therefore, the common issues associated with immobilizer programming in other vehicles are not a concern here.

Cost Expectations: As on-board programming is supported, the only cost you will incur is the purchase of the new key fob itself. As mentioned, this can range from approximately $175-$250 if purchased from Tesla. If compatible aftermarket options become available, they may be less.
