Key Service for 2009 Mercedes-Benz CLK 550
Our Mercedes‑Benz key replacement service securely cuts and programs key fobs to your vehicle’s immobilizer so you regain reliable locking, unlocking, and starting. We can also deactivate missing keys for security. We offer a fast mail‑in module option that avoids towing and dealer delays.
Common reasons you may need a replacement key:
- Lost, stolen, or physically damaged key/fob.
- “Key Not Detected/Key not recognized” messages or the vehicle not recognizing the fob for KEYLESS‑GO starting.
- Remote buttons don’t work (or work only at very short range) even after a fresh battery.
- Worn/bent blade or broken flip mechanism on older designs, making the key unreliable or unusable.
