Trims and build dates can change which fob a Avalon uses. The surest match is the FCC ID printed on the back of your current key — compare it to the code on each listing.

Toyota Avalon key replacement — what to know

Losing or breaking the key fob for your Toyota Avalon doesn't mean a costly trip to the dealer. The Avalon uses several key styles (Smart / Proximity Keys, Key Shells & Cases), and as long as the FCC ID, frequency and transponder chip match, an OEM or quality aftermarket remote will operate your locks, trunk and alarm just like the original.

At KEYHAUS we focus exclusively on remote keys, so every Avalon listing is cross-referenced to the original equipment part numbers and scored for fitment confidence. You'll see the exact FCC ID (HYQ14FBA, HYQ14FBA (shell)), the chip type, and whether the key can be self-programmed at the OBD port or needs a locksmith — before you add it to your cart.

Avalon key fob — frequently asked

How much does a Toyota Avalon key fob cost?
Replacement Avalon remotes range from $8.99 for verified aftermarket fobs to $128.99 for OEM-genuine units — a fraction of dealer pricing. Every listing shows a fitment confidence score.
Which FCC ID does my Toyota Avalon use?
Depending on trim and build date, the Toyota Avalon uses one of these FCC IDs: HYQ14FBA, HYQ14FBA (shell). Flip your current fob over to confirm the code printed on the back.
Can I program a Avalon key myself?
Others require a dealer or automotive locksmith to pair. Each product page lists the exact programming method.
What transponder chip is in the Avalon key?
These fobs use transponder chips including ID47 (Hitag-3), no chip (housing only). The chip must match for the immobilizer to recognize the key — we verify it on every listing.
What if the key doesn't fit my Avalon?
Our 30-day fitment return covers it with a free prepaid label. Confirming the FCC ID on your current fob before ordering is the surest way to get it right.
