About 911 Keys

Verified key reference for the Porsche 911 — model years, key types, and the transponder/immobilizer each generation uses. Boundary years can overlap; we confirm the exact part by VIN before dispatching.

Security System & Immobilizer

Porsche ran ID48 and ID46 chips through the 2000s before proximity fobs — serviceable with VAG-family tooling.

On the 911 specifically we see: Megamos 13 (ID13), Megamos Crypto 48 (ID48), Philips Crypto 2 (PCF7946 / ID46), Hitag Pro (PCF7945 / ID49), Hitag Pro (CMD53 / ID49). A correctly cut but unprogrammed key turns the locks and never starts the engine — programming is the half of the job that matters.

Porsche 911 Key FAQ

I lost the only key to my 911. What now?

We come to the vehicle, verify ownership, cut a new key from the VIN, and program it on-site — no tow, no dealer wait.

My 911 is push-to-start — can you program that outside the dealer?

Yes. Late models (2018–present) use a proximity smart key on Hitag Pro (CMD53 / ID49) — we carry the fobs and the programmer, and we cut the emergency blade.

Do you still stock keys for older 911s?

Yes — back to the 1998–1999 generation (transponder), and a fresh code-cut key beats any copy of a worn original.

How fast can you reach my 911 in DFW?
