Toyota Key Replacement, Key Fob Programming & Smart Key Service
TOY43 transponder keys, TOY44 remote heads, and TOY48 128-bit smart keys cut and programmed at your location across Palm Beach County.
Toyota keys evolved from the TOY43 transponder blade through the TOY44 remote head key to the high-security TOY48 keyway used on today's smart keys. The chip moved from early 4C and 4D67 transponders to 80-bit and finally 128-bit smart-key encryption, so the year and ignition type decide which key your Toyota needs.
Our mobile techs cut and program keys for the Toyota lineup most common in Palm Beach County, including the Camry, Corolla, RAV4, Tacoma, and Highlander. We carry the blanks and programming tools in the van, confirm whether your Toyota is turn-key or push-to-start, and finish most jobs curbside in one visit.
Toyota key types by generation
Toyota keys changed significantly from one era to the next. The right blank, chip, and programming path depend on the year, trim, and ignition type, which is why we ask for the details before selecting a key.
Early 2000s: TOY43 transponder keys
Toyota used the TOY43 keyway with early Texas Instruments transponders (4C, then 4D67). These start the engine only when the chip is matched to the immobilizer, even if the blade fits the door and ignition.
Late 2000s to mid 2010s: TOY44 and 80-bit remote heads
Remote head keys (such as the GQ43VT20T) combined the cut blade with lock and unlock buttons, and the transponder moved to a harder-to-clone 80-bit format. Smart keys began appearing on higher trims with the HYQ12BEL proximity fob.
Mid 2010s to present: TOY48 128-bit smart keys
Modern push-to-start Toyotas use the high-security TOY48 keyway and 128-bit smart keys (HYQ14FBA, HYQ14FBN, HYQ14FLA) with a TOY48 emergency blade inside. Lost smart keys are programmed to the specific vehicle.
Toyota key data by model
Verified blank, chip, and FCC references are marked accordingly. Where a value depends on trim, button count, or production date, confirm it from the original key, a VIN lookup, or a supplier catalog before cutting or ordering.
Data is drawn from professional locksmith key references. It is a starting point for identification, not a guarantee for your specific vehicle.

Toyota Key & Fob FAQs
Can you replace a Toyota key if I lost all of them?
Yes. We program a new key or smart key to your vehicle on site. All-keys-lost jobs on push-to-start models take a little longer because the key is programmed directly to the car.
Do you program Toyota smart keys (push-to-start)?
Yes. We supply and program proximity smart keys such as the HYQ14FBA and HYQ14FBN and cut the TOY48 emergency blade inside.
My Toyota key turns but won't start. What's wrong?
The transponder in the key has to match the immobilizer. If the blade is fine but the engine won't start, the chip may have failed and the key needs reprogramming or replacement.
Is my Camry turn-key or push-to-start?
Both exist across the years. If you insert and twist a key it is turn-key; if you press a button it is a smart key. Tell us which so we bring the correct key.
How much is a replacement Toyota key?
It depends on whether it is a transponder key, a remote head key, or a smart key, plus the year. We quote an up-front price before we head out.
Can you cut a spare Toyota key from my working one?
Yes. A spare made from a working key is the cheapest insurance against a future lockout, and we cut and program it on the spot.
Do you come to my home or workplace?
Yes. We are fully mobile and service Toyotas wherever they are parked across Palm Beach County.
Why is my Toyota smart key not detected?
It is often a dead coin battery rather than a failed fob. We can test it, replace the battery, or program a new smart key if needed.
What do you need to make a Toyota key?
The year, model, VIN, whether it is turn-key or push-to-start, and proof of ownership. A photo of your current key helps us match it.
Do you service Toyota trucks and SUVs as well as cars?
Yes. We handle the Tacoma, RAV4, Highlander, and the rest of the Toyota lineup, not just the sedans.
