A replacement Tesla key card comes from Tesla. You pair it yourself on the touchscreen. You need an already-authorized key (phone, card, or fob) to add a new one. If every key and the phone are gone, Tesla’s infrastructure owns access, not a locksmith OBD tool.
San Diego has a dense Tesla mix in La Jolla, Encinitas, Rancho Santa Fe, Carmel Valley, and Del Mar. Swift Key San Diego is a locksmith referral service. Independent locksmiths can open a Tesla door in some lockout cases. They cannot provision Tesla keys. Call (858) 400-4082 for conventional lock work or a physical lockout when Tesla roadside is not the faster path.
Three ways to access a Tesla
Phone key
The Tesla app over Bluetooth is the primary key for most owners. Dead phone often looks like a car lockout.
Key cards
Two NFC cards ship with the car. Tap the B-pillar to unlock, hold to the console to start. Add Key lives under Controls > Locks. An authorized key must be present to add another.
Optional key fob
Tesla sells a miniature Model 3 / Model Y style fob as an accessory. It also needs an existing authorized key to pair. It is not a locksmith part.
Locked out
Phone has battery. Unlock in the app.
Phone dead, card in hand. B-pillar then console.
Phone dead, both cards lost or inside. Tesla roadside at 1-800-333-3798 can push an unlock after identity checks. A driver already on the account can unlock from their app. A locksmith may reach the physical latch if other options fail. They cannot add a new card.
If the 12V battery is dead, none of the radios behave normally. See below.
What a locksmith can and cannot do
Can: physical entry when roadside is slow; house, mailbox, garage, and lock rekey on the property; key duplication for ordinary house keys.
Cannot: add a Tesla key card; program Tesla app access; replace Tesla’s accessory fob; unlock a car with a fully dead 12V the same way as a powered car.
The 12V battery
Every Tesla has a small 12V pack for electronics besides the drive battery. When it dies, handles stay in, the screen stays dark, phone and card stop working.
Many Teslas have an external 12V charge point behind the front tow-hook cover. A jump pack can restore enough power to unlock. Tesla roadside walks this. Once in, do not drive on a failing 12V. Service the pack.
Adding a replacement card yourself
- Order a card from Tesla’s shop.
- On the car: Controls > Locks > Add Key.
- Present an existing authorized key at the console when prompted.
- Tap the new card on the console reader.
- Name the key if you want.
If both cards are gone and the app is not set up, Tesla verifies identity and resets access through service. That is slow. Order a spare while you still have one working key.
Home security for Tesla owners
Move-in rekey, Grade 1 deadbolts, mailbox locks, and the house-to-garage door are ordinary locksmith jobs. The car’s key system is not.

Frequently asked questions

How much does a Tesla key card cost?

What if I lose all Tesla keys?
Tesla identity verification and service. A locksmith may get you physically in. Restoring keys is Tesla’s job.
Is the accessory fob worth it?
Useful for valets or anyone not on the app, or if you want a physical object. It does not add functions the phone key lacks.
