2017 Porsche 911 Key Replacement Process & Programming Steps
- 1
Verify Ownership & Access Porsche 911 Systems
We confirm vehicle ownership (registration document or ID), then connect our Porsche PIWIS-compatible equipment to your 2017 Porsche 911's OBD port to access the immobiliser and KESSY/BCM2 module.
- 2
Generate Key Code from VIN
Using your vehicle's VIN, we generate the correct key code for your 2017 911. For all-keys-lost situations, this is how we create a new KESSY proximity smart key from scratch — no original key needed.
- 3
Cut the Key Blade On-Site
We cut the key blade to factory specification using precision key-cutting equipment in our service vehicle. For the Porsche 911, the blade profile must match the door and ignition barrel exactly.
- 4
Programme Transponder & Smart Key
The transponder chip and remote/smart key functions are programmed directly to your 2017 Porsche 911's immobiliser using Porsche PIWIS. This includes central locking, keyless entry (if equipped), and push-button start synchronisation.
- 5
Full System Diagnostic Test
Before we leave, we run a complete diagnostic scan on your Porsche 911 to verify the key is fully functional — lock, unlock, boot release, push-button start, and immobiliser recognition all confirmed working.

Common 2017 Porsche 911 Key System Problems We Fix
Specialist diagnosis for the issues that affect this specific model year
Keyless Entry Stopped Working
If your 2017 Porsche 911 keyless entry has stopped working but the key still starts the car, the key may have de-synchronised from the vehicle. We re-programme the keyless entry functions on-site using Porsche PIWIS without needing a new key.
Key Won't Turn in Ignition
If your 2017 Porsche 911 key won't turn in the ignition, the key blade may be worn or the ignition barrel damaged. We can cut a new blade to factory spec or repair the ignition barrel without replacing the entire assembly.
