Losing the key to a Lexus RX is stressful, especially when the vehicle is stuck in a parking lot, at home, or far from a dealership. Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and we are fully mobile: we come to wherever the RX is parked. We do not operate a shop, so there is nothing to tow and nothing to carry in.

The RX has used proximity Smart Key systems across the 2007-2024 model years, but the exact key, chip and programming depend on the trim and VIN. Before we cut or program anything, we confirm the correct key by VIN so the fob matches your vehicle.

Whether you need a spare while you still have a working key, or you have lost every key and the RX will not start, we can help. Adding a spare is usually simpler and less costly than an all-keys-lost situation, so it is worth acting before the last key goes missing.

Lexus RX key systems by year

Earlier years

These RX models use a Proximity Smart Key with push-button start. The fob lets the vehicle detect the key nearby, and it holds a mechanical emergency blade that can be used to open the door if the fob battery is weak or the fob is not responding. Replacement generally involves sourcing a fob that matches your vehicle, cutting the emergency blade if needed, and programming the fob to the vehicle. The exact key and programming depend on trim and VIN, and we confirm the correct key by VIN before cutting. This applies to both a spare key and all keys lost.

Recent years

Newer RX models use an encrypted proximity Smart Key fob, designed with stronger security between the fob and the vehicle. Both add-a-key (spare) and all-keys-lost situations are confirmed by VIN before we proceed. Replacement generally means obtaining the correct encrypted fob for your vehicle and programming it so the RX recognizes it. Exact requirements vary by trim and VIN, so we verify everything first rather than guessing.

Exact key, chip and programming vary by trim and VIN — we confirm the right key for your car before cutting.

Lexus RX keys — FAQs

Can you make a Lexus RX key if I have lost all my keys?
Yes. All-keys-lost service is something we handle on-site. We verify ownership, confirm the correct key by VIN, then prepare and program a new fob at your vehicle. Call (323) 997-8867 any time, day or night.
Is it better to add a spare key before I lose my last one?
Yes. Adding a spare while you still have a working key is generally simpler than starting from all keys lost. We still confirm the correct key by VIN, since the exact key and programming depend on trim.
What if I never had an original key, such as with a used RX?
We can still help. With proof of ownership, photo ID and the VIN, we confirm the correct key for your vehicle and program a new one, even if you have no original.
What is the difference between push-button start and the bladed key in my fob?
The RX uses push-button start with a Smart Key, so you do not insert a key to drive. Earlier-year fobs also contain a mechanical emergency blade that opens the door if the fob is not working. We can supply the blade where your fob type includes one.
Do I need to tow my Lexus RX anywhere?
No. We are fully mobile with no shop, so we come to your RX wherever it is parked in Greater Los Angeles or Ventura County.
What do you need from me to get started?
Proof of ownership, photo ID and the VIN. The VIN lets us confirm the correct key before we cut or program anything, since the key, chip and programming depend on trim and VIN.
How long does the service take?
It depends on the model year, the key type and whether it is a spare or all keys lost. Your technician will explain what to expect once the VIN is confirmed. Call (323) 997-8867 to get started.
