Volkswagen Jetta Key Replacement
Volkswagen Jettas have been on Dallas–Fort Worth roads since the 2005 era, and across 3 key generations this model has used 2 different key systems — remote flip key; smart key (prox) / flip. Whichever yours is, DFW Keys 4 Cars cuts and programs it at your location, 24/7: spare keys, lost-everything replacements, fob programming, and lockouts. Call (214) 717-6398.
About Jetta Keys
The table below is our verified key reference for the Volkswagen Jetta — model years, key types, and the transponder/immobilizer family each generation uses. Generations overlap at boundary years, and trim levels (keyed vs. push-to-start) can differ within the same year, so we always confirm the exact part by VIN before dispatching.
| Model / Generation | Years | Key Type | Transponder / Immobilizer | Blade / FCC |
|---|---|---|---|---|
| Jetta | 2005–2010 | Remote flip key | Megamos Crypto ID48 (VW-CAN / precoded) | HU66 |
| Jetta | 2011–2018 | Remote flip key | Megamos Crypto ID48 (precoded) | HU66 |
| Jetta | 2019–2024 | Smart key (prox) / flip | Megamos AES ID49/ID88 (MQB) | HU162T |
Security System & Immobilizer
VW’s immobilizer generations (Immo 1 through 4/5) ran on Megamos ID48 “precoded” chips before the MQB platform moved to Megamos AES — the era determines whether a key can be cloned or must be dealer-style programmed, and we handle both.
On the Jetta specifically, the immobilizer families we see are: Megamos Crypto ID48 (VW-CAN / precoded), Megamos Crypto ID48 (precoded), Megamos AES ID49/ID88 (MQB). A key that is cut correctly but not programmed to this system will turn the locks and never start the engine — programming is the half of the job that matters.

Volkswagen Jetta Key FAQ
I lost the only key to my Jetta. 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 — this is our most common Jetta call.
My Jetta is push-to-start. Can you really program that outside the dealer?
Yes. Late-model Jettas (2019–2024) use a proximity smart key on the Megamos AES ID49/ID88 (MQB) system — our trucks carry the fobs and the programmer. We cut the emergency blade too.
My Jetta is older — do you still stock keys for it?
Yes. We carry blanks and chips going back to the 2005–2010 generation (remote flip key), and a code-cut fresh key usually turns a worn lock better than any copy of your worn key.
