The E-Class has used encrypted key systems across model years 2007 to 2024, so a replacement is not a simple copy at a hardware counter. The key must be matched to your car's immobilizer, and the exact key, chip and programming depend on your trim and VIN. Before anything is cut or programmed, we confirm the correct key by VIN.
Whether you need a spare because you only have one key, or you have lost every key and the car will not start, we handle both. Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and we are fully mobile: there is no shop to tow your car to. A technician comes to wherever the E-Class is parked, day or night.
Having a spare made while you still hold a working key is usually simpler and less stressful than an all-keys-lost situation. If you have already lost everything, we can still help on site, provided you can show ownership and we can verify the VIN.
Mercedes-Benz E-Class key systems by year
Earlier years: Key fob with insert or push-button start; high-security encrypted immobilizer
Earlier E-Class models use a key fob that may carry a mechanical insert key, or a push-button start arrangement, paired with a high-security encrypted immobilizer. The car will not start unless the key's electronic identity is accepted by the vehicle. Replacement generally involves obtaining the correct key for your car, cutting the insert blade where one applies, and programming the key to the vehicle. The exact key type, chip and procedure depend on trim and VIN, so we confirm the correct key by VIN before cutting. This applies to spare keys and to all-keys-lost situations alike.
Recent years: Encrypted proximity key
Recent E-Class models use an encrypted proximity key, which lets you unlock and start the car without removing the fob from your pocket or bag. These keys are tied securely to the vehicle, and programming is confirmed by VIN. Replacement generally means sourcing the right proximity key for your car and programming it so the vehicle recognizes it, while verifying ownership first. Because the exact key and programming depend on your trim and VIN, we confirm the correct key by VIN before proceeding. We can add a spare or replace keys when all have been lost.
Exact key, chip and programming vary by trim and VIN — we confirm the right key for your car before cutting.
