Key types by year, side by side
Both vehicles changed key technology over their runs, so the right blank, chip, and programmer depend entirely on your model year. Here is what each one uses:
Audi Q7
HU66 blade, Megamos ID48 (8E) chip. Flip-key remote FCC: IYZ-3314.
HU162T (MQB) emergency blade, Megamos AES. FCC: IYZFBSB802 / 4M0959754.
BMW X5
HU92 blade, early transponder chip.
CAS2/CAS3 system, comfort access available.
CAS4/FEM/BDC system. Standard comfort access.
Which is simpler or quicker to key?
Neither the Audi Q7 nor the BMW X5 typically needs a dealer for routine key work. Both are mobile, on-site jobs: a spare comes from a working key in a single visit, and a lost-all-keys situation means reading the immobilizer PIN through the OBD-II port before enrolling the new key.
The quirk that trips people up on each
- Component protection on MQB cars. On 2017+ Q7s an all-keys-lost can trip Audi component protection; without the correct online tooling the modules reject the new key even after it's cut perfectly.
- Four possible modules. The X5 ranges from an early HU92 transponder to CAS4/FEM/BDC across its runs, so identifying the exact system is essential before any key is enrolled.
How a key job runs on either one
The path works the same way on both. The simplest job on either vehicle is a planned spare made while you still have a working key, because that key acts as the authentication seed and the work is short. A lost-all-keys situation takes more steps on either one, since the programmer has to read the immobilizer PIN before it can enroll a new key. We confirm the exact part by VIN before we dispatch, so the right blank, chip, and programmer are on the truck when we arrive.

Frequently asked: Audi Q7 vs BMW X5 keys
Is the Audi Q7 or the BMW X5 simpler to make a key for?
They are comparable. A spare made from a working key is the simplest path on either vehicle; a lost-all-keys situation takes more steps because we read the immobilizer PIN first. We confirm the exact path by VIN before dispatching.
Can you make a key for both on-site in Statesboro?
Yes. Both the Audi Q7 and the BMW X5 are handled by our mobile unit at your location for the large majority of year ranges. Any exception that needs dealer coordination is flagged on the phone when we confirm your VIN, so the work is set up correctly before we arrive.
Do I need the original key to get a replacement?
No. With a working key we make a spare in a single visit because the original acts as the authentication seed. With no key at all, we read the immobilizer PIN and build a key from your VIN. Both vehicles support both paths.
