About KEYHAUS
We do one thing, deeply: replacement car remote keys, matched to your exact vehicle and scored for fitment before you buy.
Why a specialist?
General parts stores list hundreds of thousands of SKUs and leave fitment to you — which is exactly why replacement keys are one of the most-returned auto parts online. We took the opposite approach: a focused, deep catalog of keys we can actually verify, instead of everything under the sun.
How we match keys
Every key on KEYHAUS is matched to your vehicle by three things that actually determine whether a fob will work:
- FCC ID — the regulatory code printed on the fob, the most reliable fingerprint of an exact replacement.
- Frequency — the radio frequency your vehicle's receiver listens for.
- Transponder chip — the immobilizer chip your car's security system must recognize.
We surface all three up front, plus a fitment confidence score so you're never guessing.
What we stock
A curated mix of OEM keys and verified aftermarket from trusted names (Xhorse, KEYDIY, Autel). Every listing tells you the programming method — OBD self-program, locksmith, or dealer — before you buy, so there are no surprises in your driveway.
The fitment-confidence loop
When a key is returned for a fitment reason, our system automatically lowers that key's confidence score and flags its vehicle matches — so the catalog gets more accurate over time, not less. Your returns make the next customer's match better.
Locksmith-led support
