Lexus Key Replacement
$200 - $450 | 30-60 minutes | Available 24/7
Triton Locksmith replaces Lexus keys and Smart Key fobs for $200-$450 at your location. IS, ES, GS, LS, RX, NX, UX, GX, LX, and LC. Lexus uses Toyota's key platform with premium fob housings. Same 4D, G, H, and 8A chip programming. 30-60 minutes on-site.
What Lexus Key Systems Does Triton Locksmith Program?
Lexus is Toyota's luxury division and uses the identical key/immobilizer technology. The chips, IMMO modules, and programming protocols are the same. The difference is the key shell design (Lexus fobs have a different shape and finish) and the price of the blank (Lexus fob housings cost more). Here's the system breakdown:
- 4D chip (2001-2012): Texas Instruments 4D67/4D68 transponder. Used on older IS 250/350, ES 330/350, GS 300/350, RX 300/330/350, GX 470, LX 470. Same as equivalent-era Toyota models. Blade blank: TOY48. $200-$275.
- G chip / H chip (2010-2019): Toyota-proprietary DST80 encryption. Used on IS 250/350/200t, ES 350, GS 350, NX 200t/300, RX 350/450h, GX 460, LX 570, RC. Same G/H chip as Toyota Camry and RAV4 of the same era. $225-$325.
- 8A chip / Hitag Pro AES (2018+): Philips/NXP 8A with AES-128 encryption. Used on ES (2019+), IS (2021+), NX (2022+), RX (2023+), UX, LC. The newest and most secure. Requires our Autel IM608 Pro with the latest firmware. $300-$450.
- Smart Key (proximity/push-to-start): Standard on all Lexus models since approximately 2006-2010 depending on the model. Uses 125 kHz proximity + 315 MHz remote. Programming through the Smart Key ECU via OBD-II.
The Lexus RX is our most common Lexus key call in South Florida, followed by the ES and NX. Boca Raton and Palm Beach have high Lexus density. We carry blanks and fobs for all current and recent models.
How Much Does a Lexus Key Cost?
$200-$450 from Triton Locksmith. $400-$800 at the Lexus dealer.
- 4D transponder key: $200-$275
- G/H chip Smart Key fob: $275-$375
- 8A chip Smart Key fob (2018+): $350-$450
- Emergency blade (hidden inside fob): $25-$50
- Lexus dealer price: $400-$800 + tow + 3-7 day wait
Lexus keys cost $50-$100 more than equivalent Toyota keys because the fob housing is different (higher-quality materials, Lexus-specific shape). The internal electronics and programming are identical. You're paying for the shell, not the technology.
Why Does Triton Locksmith Cost Less Than the Lexus Dealer?
Same technology, less overhead. The Lexus dealer uses the same OBD-II diagnostic process we use. They read the IMMO module, generate the key data, and write it to the fob. Same steps. But they do it in a $10 million dealership with 50 employees. We do it in your driveway with a van and professional tools. Lower overhead = lower price. The key works identically.
Plus we come to you. No towing the car to the dealership ($100-$200 saved). No leaving it for days. No rental car. One visit, one hour, done.

Is Lexus Key Programming the Same as Toyota?
Internally, yes. The IMMO module, chip types, and OBD-II programming protocols are shared between Lexus and Toyota. Our Autel IM608 Pro treats them as the same platform. The only differences are the fob shell design and the vehicle model selection in the diagnostic software. If we can program a Toyota Camry, we can program a Lexus ES. Same security, same process.
