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.
Mercedes-Benz GLE
HU64 emergency blade, FBS3 system. Dealer / advanced tool for add-key.
HU64 emergency blade, FBS4 system. Dealer coordination typical.
Which is simpler or quicker to key?
On a lost-all-keys job the Audi Q7 is usually the more straightforward of the two, since it is typically handled entirely on-site through the OBD-II port. Some Mercedes-Benz GLE year ranges can require a manufacturer PIN or dealer coordination, which adds steps to the job. With a working key in hand, either one has a spare programmed on-site the same visit.
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.
- FBS4 lockdown. 2020+ GLE all-keys-lost generally needs Mercedes dealer coordination; don't lose your last fob, because an add-key is far easier than starting from zero.
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 Mercedes-Benz GLE keys
Is the Audi Q7 or the Mercedes-Benz GLE simpler to make a key for?
For a routine spare both are similar, but the Audi Q7 tends to be the more straightforward of the two on a lost-all-keys job, because some Mercedes-Benz GLE years can need dealer or PIN coordination. We confirm the exact path for each by VIN before dispatching so there are no surprises.
Can you make a key for both on-site in Statesboro?
Yes. Both the Audi Q7 and the Mercedes-Benz GLE 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.
