2019 Lexus LX replacement key fob with no original from EZ Car Keyz Oxnard CA
🔧 PRO TIP
The 2019 LX 570 runs the Toyota/Lexus H-8A (128-bit AES) transponder chip inside the HYQ14FBA smart key at 315 MHz. Part number 89904-30A30 covers the base fob, but some builds shipped with 89904-78470 depending on trim date. A dying CR1632 throws "Key not detected" or "No key detected" on the dash multi-info display and kills the touch-to-unlock range before anything else. Swap the battery first, but seat it flat. A cockeyed CR1632 mimics a dead fob perfectly.

2019 Lexus LX Smart Key Replacement - Fast, Affordable & Professional

A guy called me from an underground garage near Oxnard Beach Park around 10 at night. His only smart key for a 2019 LX 570 was gone. Checked his pockets, the elevator, the stairwell, retraced his steps twice. Nothing.

He was ready to have the thing towed just to get it somewhere safe. Didn't know his VIN off the top of his head. Didn't have his registration in his wallet.

I walked him through it on the phone. Told him to check the base of the windshield, driver's side. He found the VIN. Then I had him pull up his insurance app, and the registration was right there. With that VIN I already knew his key type, the board number on his smart key ECU, and which HYQ14FBA fob to prep before I left.

Under the garage lights I used my VVDI Key Tool to generate a fresh H-8A transponder matched to his immobilizer ECU. Cut the emergency insert blade, programmed the 4-button remote, synced proximity detection. Walked every door handle, tested the hatch, hit the start button.

He just stood there watching the dash like he expected it to argue. It didn't.

He drove home that night. The old missing fob got erased from the system so it can't start anything. The whole job took less time than calling for a tow, and cost a fraction of what the dealer would have quoted, assuming they were even open at that hour.

“The dealership quoted me $600 for a new Honda key. EZ Car Keyz did it for $225, same day, cut and programmed at my house. Works perfectly. Everyone should know this is an option.”

Lexus LX Mobile Service FAQ

Real costs, no dealer surprises

I lost my only key for a 2019 Lexus LX. Can you make one on site?
Yep. All-keys-lost on the 2019 LX 570 is a standard call for me. I connect through the OBD-II port, reset the smart key ECU (part number 89990-60060 on most J200-series LX builds), generate a new H-8A transponder, program the HYQ14FBA fob, and cut the emergency insert blade right there. The old missing fob gets wiped from the system so nobody can use it. There's a timed security handshake built into the registration process, so expect about 30 to 45 minutes on site. You don't need a tow, and you don't need to wait for a dealer appointment.
Is a locksmith cheaper than going through Lexus for a replacement smart key?
Does the price include cutting, programming, and the fob itself?
My 2019 LX says "Key not detected" but the fob battery is new. What's going on?
Can I use a Toyota Land Cruiser 200 smart key in my 2019 Lexus LX 570?
