🛠️ Programming instructions

🔑SMART KEY PROGRAMMING - OBD / SEED-KEY

This Toyota RAV4 key is programmed to the vehicle with an OBD diagnostic/key tool. Add-key needs a working key present; all-keys-lost is done via OBD where the platform supports it.

Connect the tool connect an OBD key programmer that covers Toyota RAV4 RAV4 (XA50), European and Gulf build and select the correct 433 MHz smart key profile.
Program the key add the key with a working key present, or run the all-keys-lost routine via OBD where the platform allows.
Cut the blade and test cut a TOY48-profile blade to the customer's bitting, fit it, then test remote, immobiliser, and start on the vehicle.
Verify coverage first: This is a Toyota 8A DST-AES smart key. Adding a key needs a tool with current Toyota 8A coverage and a working key present; an all-keys-lost job normally needs a seed-key or simulator route plus the vehicle security code rather than plain OBD. Verify tool coverage for the exact model year and market before quoting.

Frequently Asked Questions

Common questions about this product

It fits the 2019–2022 models that match part number 8990H-42190. Verify that FCC or part number and the 433 MHz frequency against the customer's original key before ordering, since these platforms use more than one key variant across trims and model years.
No. It is supplied unprogrammed and must be coded to the vehicle by a locksmith with an OBD key tool. Add-key requires a working key present; all-keys-lost is done via OBD where the Toyota RAV4 platform supports it, sometimes needing a security code.
It carries a 8A (Toyota H, DST-AES) transponder on 433 MHz. That is the correct combination for the immobiliser on these vehicles, so no separate transponder is sourced - but the key must still be programmed to the specific vehicle before it will start the engine.
No. The TOY48-profile blade is sold separately and cut to the customer's original bitting, or you can transfer the customer's existing blade if it is sound. Fit it to the key after programming so the finished key works mechanically as well as electronically.
Yes. It is a genuine factory (OEM) unit, supplied new and unused, matching part number 8990H-42190. Verify part number 8990H-42190 against the customer's original key before ordering to be sure of the exact variant for their specific vehicle, model year, and trim level.
It is supplied new and unused. Like any replacement Toyota RAV4 key of this type, it still has to be programmed to the vehicle, and cut to the customer's bitting where a blade applies, before it will operate and start the vehicle.
Match the FCC ID, part number, frequency, and button count printed on or programmed into the customer's original key against this listing. On these platforms a single vehicle family spans several key variants, so verifying those details prevents ordering a part that will not program.
