Lexus ES Key Replacement
Lexus ESs have been on Dallas–Fort Worth roads since the 1998 era, and across 5 key generations this model has used 3 different key systems — transponder ignition key; transponder / remote-head key; smart access proximity (push-button). Whichever yours is, DFW Keys 4 Cars cuts and programs it at your location, 24/7: spare keys, lost-everything replacements, fob programming, and lockouts. Call (214) 717-6398.
About ES Keys
The table below is our verified key reference for the Lexus ES — model years, key types, and the transponder/immobilizer family each generation uses. Generations overlap at boundary years, and trim levels (keyed vs. push-to-start) can differ within the same year, so we always confirm the exact part by VIN before dispatching.
| Model / Generation | Years | Key Type | Transponder / Immobilizer | Blade / FCC |
|---|---|---|---|---|
| ES | 1998–2003 | Transponder ignition key | Texas ID 4C | TOY40 |
| ES | 2004–2006 | Transponder / remote-head key | Texas Crypto 4D (4D68, DST80 “G”) | TOY48 |
| ES | 2007–2012 | Smart Access proximity (push-button) | Texas Crypto 4D (4D68, DST80 “G”) | TOY48 (insert) |
| ES | 2013–2018 | Smart Access proximity (push-button) | Texas DST-AES 128-bit (“H”, Page1 39) | TOY48 (insert) |
| ES | 2019–2025 | Smart Access proximity (push-button) | Texas DST-AES 128-bit (“H”, Page1 39) | TOY48 (insert) |
Security System & Immobilizer
Lexus shares Toyota’s immobilizer lineage — 4C, 4D67, G and H transponder eras — topped by the Smart Access proximity system on push-to-start models. Luxury badge, familiar engineering: all of it programs on-site with the right tools.
On the ES specifically, the immobilizer families we see are: Texas ID 4C, Texas Crypto 4D (4D68, DST80 “G”), Texas DST-AES 128-bit (“H”, Page1 39). A key that is cut correctly but not programmed to this system will turn the locks and never start the engine — programming is the half of the job that matters.

Lexus ES Key FAQ
I lost the only key to my ES. What now?
We come to the vehicle, verify ownership, cut a new key from the VIN, and program it on-site. No tow, no dealer wait — this is our most common ES call.
My ES is push-to-start. Can you really program that outside the dealer?
Yes. Late-model ESs (2019–2025) use a proximity smart key on the Texas DST-AES 128-bit (“H”, Page1 39) system — our trucks carry the fobs and the programmer. We cut the emergency blade too.
My ES is older — do you still stock keys for it?
Yes. We carry blanks and chips going back to the 1998–2003 generation (transponder ignition key), and a code-cut fresh key usually turns a worn lock better than any copy of your worn key.
How fast can you reach my ES in DFW?
We dispatch the nearest mobile unit across the whole metroplex, 24/7. Call (214) 717-6398 with your location and we’ll give you an honest ETA.
