Lexus is Toyota's luxury brand, and under the leather they share most of their key systems. A Camry and an ES are close cousins to a locksmith. Here is what your era means for a lost key.
Your Key by Era
| Years | Key system | What it means |
|---|---|---|
| Late 1990s to late 2000s | 4C or 4D chip key | Chip in a plastic head. Many had a black master key and a gray valet key. |
| About 2010 to 2014 | G chip key | Look for a small G stamped on the blade near the head. |
| About 2014 to 2010s | H chip key | An H stamped on the blade. Needs a newer blank and tool. |
| 2000s to now | Smart key push-start | Common across Lexus earlier and most Toyota models today. Some Lexus models also offered a card key. |
What a Locksmith Can Usually Do
Spares on chip keys and most smart keys are routine. All-keys-lost on some smart key models takes extra steps on the car, which raises the price.
When the Dealer Is the Better Call
Some all-keys-lost smart key jobs on certain models, and some of the newest models, may still be easier at the dealer.
Tips Worth Knowing
- Check the letter on your blade. G or H tells a locksmith which blank to bring, which saves a second trip.
- Dead smart key battery? Touch the Toyota or Lexus logo side of the fob to the start button, then press the brake and start.
- On older Toyotas, a gray valet key may not open the trunk or glove box. That is by design, not a defect.
