A Smart Key is the type of key your 2020 Lexus LX uses. It contains a programmed transponder chip that communicates with your vehicle's immobilizer system to authorize the engine to start. It also has 4 buttons for remote lock, unlock, and other functions. Without proper programming, even a perfectly cut key will be rejected by your Lexus security system. We program everything on site so your new key works exactly like the original.

2020 Lexus LX Smart Key Replacement - Fast, Affordable & Professional

I come to your GPS pin. You drop a pin where the car is, I drive there, and the job happens wherever your 2020 Lexus LX sits. Parking lot, vineyard, mountain road. The car doesn't move.

A wine taster at a vineyard outside Rancho Santa Fe lost his only Lexus key somewhere between the tasting room and the parking area. No dealer within 25 miles, no locksmith nearby. His car sat in a gravel lot.

He texted me his GPS pin. I drove out with everything for his LX already loaded. I used my ACDP to back up the smart ECU data, then decoded the lock and cut a fresh blade on-site. His smart key, FCC ID HYQ14FBA, was a 4-button proximity fob for the RX platform that I built from scratch at the vineyard.

His car started in that gravel lot. Total was around $306. A dealer would have charged $568 plus a tow from a vineyard with no paved access for a flatbed.

Lexus LX Mobile Service FAQ

Real costs, no dealer surprises

Do I have to go to the Lexus dealer to get a replacement key?▼

No. A qualified mobile locksmith can cut and program a Smart Key for your 2020 Lexus LX right where the vehicle sits. Lexus owners often assume the dealer is the only option, but that is not the case for the vast majority of models. The dealer route means scheduling an appointment, towing if you have no working key, and sometimes waiting weeks for the fob to arrive. During 2022 to 2024, NX and RX owners reported getting only one key at delivery and waiting three to six months for the second.
