How to Verify This Is the Right Key for Your Toyota
Before purchasing a replacement transponder chip key for your 2017 Toyota 4Runner, verify these details to ensure a perfect match:
5-Point Compatibility Checklist
- Verify Year, Make & Model — Confirm this key is listed for your exact 2017 Toyota 4Runner. Even within the same model, different trim levels or production dates may use different key types. Check your owner’s manual or the sticker on the driver’s door jamb for your exact model year.
- Match the FCC ID — This is the most reliable way to guarantee compatibility. Open your current key fob and look for the FCC ID printed on the back of the case or on the circuit board inside. This listing’s FCC ID is Not. Make sure it matches your existing key’s FCC ID exactly. The FCC ID identifies the exact radio transmitter — if the FCC IDs match, the keys are functionally identical.
- Check the Part Number (MPN) — The manufacturer part number (also called OEM part number or MPN) is another way to verify compatibility. This key’s part number is 89785-08040. You can find your vehicle’s correct part number in the owner’s manual, by searching with your VIN at a Toyota parts department, or on your existing key.
- Count the Buttons — Make sure the replacement has the same number of buttons in the same layout as your current key. Common configurations: 3-button (Lock, Unlock, Trunk/Panic), 4-button (Lock, Unlock, Trunk, Panic), 5-button (adds Remote Start). A key with different buttons may still work for basic functions but won’t have all features.
- Confirm the Key Type — Your Toyota may use different key types depending on the trim level:
- Transponder chip key — Traditional metal key with an embedded chip. Requires programming to start the engine.
- Key fob remote — Plastic remote for lock/unlock/trunk. Works alongside a separate ignition key.
- Remote head key / flip key — Combination key blade + remote in one unit.
- Smart key / proximity key — Push-button start. Stays in your pocket — the car detects it wirelessly.
Make sure you’re ordering the correct type for your 2017 Toyota 4Runner. If your car has push-button start, you need a smart/proximity key. If you turn a physical key to start, you need a transponder or remote head key.

Programming Guide: 2017 Toyota 4Runner Transponder Chip Key
✓ This key CAN be self-programmed at home — no locksmith needed!
Good news — your 2017 Toyota 4Runner supports on-board key fob programming. You can program this transponder chip key yourself in about 5-10 minutes with no special tools.
Step-by-Step Programming Instructions
- Open and close driver’s door 2 times.
- Insert key in ignition, pull out. Repeat 2 times.
- Open and close driver’s door 2 times.
- Insert key in ignition.
- Close driver’s door.
- Turn ignition ON and OFF once.
- Turn ignition ON and OFF again.
- Remove key from ignition.
- Door locks should cycle — programming mode active.
- Press LOCK and UNLOCK on new remote simultaneously for 1.5 seconds.
- Press LOCK button alone. Locks cycle to confirm.
- Open driver’s door to exit programming mode.
Tips for Successful DIY Programming
- Follow timing exactly — The ignition cycle timing is critical. Use a stopwatch if needed.
- Have ALL your remotes ready — Programming mode may erase existing fobs. Reprogram old ones in the same session.
- Fresh batteries — Make sure both the new key fob battery and your car battery are in good condition.
- Close all doors — Most procedures require all doors to be fully closed and latched.
- Try up to 3 times — If it doesn’t work the first attempt, try again. Timing precision matters.
- Check your owner’s manual — Some models have specific variations of the general procedure.
Important: Remote vs. Transponder Programming
DIY self-programming typically covers the remote functions only (lock, unlock, trunk, panic). If your key also has a transponder chip (needed to start the engine), that chip may need separate programming by a locksmith — even if the remote buttons program successfully at home. If your new key unlocks the doors but won’t start the car, the transponder chip likely needs professional programming ($50-$75 at a locksmith).
