How to Verify This Is the Right Key for Your Lexus
Before purchasing a replacement key fob remote for your 2003 Lexus Is300, verify these details to ensure a perfect match:
5-Point Compatibility Checklist
- Verify Year, Make & Model — Confirm this key is listed for your exact 2003 Lexus Is300. 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 Hyq1512V. 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 89070-53531. You can find your vehicle’s correct part number in the owner’s manual, by searching with your VIN at a Lexus 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 Lexus 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 2003 Lexus Is300. 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.

Tip: If you’re unsure, take a photo of your current key (front and back) and compare it to the product images above. The FCC ID is the single most important number to match.
Not Sure Which Key You Need?
- Check your existing key — Flip it over and look for the FCC ID and part number printed on the case or circuit board.

Programming Guide: 2003 Lexus Is300 Key Fob Remote
✓ This key CAN be self-programmed at home — no locksmith needed!
Good news — your 2003 Lexus Is300 supports on-board key fob programming. You can program this key fob remote yourself in about 5-10 minutes with no special tools.
Step-by-Step Programming Instructions
- Open/close driver’s door 2 times.
- Insert/remove key from ignition 2 times.
- Open/close driver’s door 2 times.
- Insert key, close door, turn ON-OFF, ON-OFF.
- Remove key. Locks cycle.
- Press LOCK+UNLOCK together 1.5 sec on new remote.
- Press LOCK alone. Locks confirm.
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).
