Independent service · not affiliated with Tesla
Your Tesla lost its connection.
We find out why — and fix it right.
When the car's security certificate expires, the app, over-the-air updates and remote diagnostics stop — but the car still drives. We read its real status remotely and arrange renewal through a legitimate channel.
No donor certificates · you pay after the result where possible
What an expired certificate changes

- Key card and phone key
- Charging
- Climate and local controls
The certificate is the car's own ID for its secure login to Tesla's servers. When it expires the login simply fails — nothing is broken in the car itself.
How it works
- 01
Tell us the car
VIN, model, year, country and whether it's a US-import or European car.
- 02
We read the certificate
Remotely, over a diagnostic cable, we read the real expiry dates — no guessing.
- 03
We arrange renewal
Through a legitimate channel for your car's market. If only Tesla can do it, we tell you plainly.
- 04
You're reconnected
App, updates and diagnostics come back. We confirm before you consider it done.
Honest pricing
Diagnosis
Flat fee
We read the certificate status and tell you exactly what's wrong and whether it can be renewed.
Renewal
Quoted after diagnosis
Priced once we confirm your car's market. Payment after the result wherever the channel allows.
No donor certificates, ever. A donor certificate puts another car's identity on yours — it shows the wrong VIN, re-expires, and breaks app and update matching. We don't offer it and advise against it.
Questions
Are you Tesla, or Tesla-authorised?
No. teslacerts.net is an independent service, not affiliated with, authorised by, or endorsed by Tesla, Inc.
Do you use donor certificates?
No. We only arrange renewal of your car's own certificate through a legitimate channel.
Can I keep driving meanwhile?
Yes. An expired certificate affects connectivity, not driving.
What if only Tesla can renew it?
For some cars and markets, Tesla's own service is the only route. If so, we tell you upfront and don't charge for work we can't do.
