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:
Chevrolet Impala
B99 / B111 blade, PK3 chip. Remote FCC: KOBGT04A / OUC60270.
Flip-key FCC: OHT01060512; proximity (LTZ/Premier) FCC: HYQ4AA.
Toyota Avalon
TOY43 blade, 4D67 chip. Smart-key FCC: HYQ14AAB.
TOY48 emergency blade, G-chip. FCC: HYQ14FBA.
TOY48 emergency blade, H-chip. FCC: HYQ14FBC / HYQ14FBE.
Which is simpler or quicker to key?
Neither the Chevrolet Impala nor the Toyota Avalon 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
- Worn ignition on W-body cars. High-mile 2006-2013 Impalas wear the cylinder until even a fresh key catches; a cylinder rebuild on-site beats chasing key after key.
- G-chip vs. H-chip. The Avalon's smart key changed chip type between generations; the wrong chip won't authenticate even with the right blade.
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: Chevrolet Impala vs Toyota Avalon keys
Is the Chevrolet Impala or the Toyota Avalon 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 Chevrolet Impala and the Toyota Avalon 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.
