🔧 PRO TIP
The 2003 Highlander runs a split setup: the ignition key carries a transponder chip for the immobilizer, and the remote fob is a separate unit on the same keyring. They work independently. If the engine cranks but dies right away, that is the immobilizer not reading the chip in the key blade, not a fob problem. If the remote stops locking and unlocking but the car starts fine, that is purely the fob. CR2032 is the battery in this fob. Swap it before you do anything else. A dying CR2032 on these will kill range first, then cause intermittent non-response, then go completely dead. The fob and the transponder key are separate problems with separate fixes.

2003 Toyota Highlander Remote Replacement - Fast, Affordable & Professional

Out in Fanita Ranch, Santee, a guy called me from the side of the road with half a key in his hand. The other half was still in the ignition cylinder of his 2003 Toyota Highlander. He had already called one other locksmith who went straight to quoting him a full ignition replacement, drilling included.

I told him to sit tight.

When I pulled up, I could see the break was clean, right at the shoulder of the blade. That is actually the better scenario. I used a blade extraction tool sized for Toyota's keyway, working carefully around the wafer stack to get purchase on the broken fragment without disturbing the tumblers. It took a few minutes of patience. The fragment came out intact.

From there I decoded the lock from the wafer positions, cut a fresh key blade to match, and enrolled the new transponder chip through the OBD port so the immobilizer would recognize it. The fob on his keyring was untouched and still working fine since the remote is its own separate unit on this generation.

No drilling. No cylinder swap. His original lock worked with the new key just the same as it always had. The other locksmith's plan would have cost him significantly more and left him with a replaced ignition that had no reason to be replaced. He saved a good chunk going the non-destructive route.

That job is a good reminder: the first quote you get over the phone is not always the right call.

Toyota Highlander Mobile Service FAQ

Real costs, no dealer surprises

What is the cheapest way to replace my 2003 Highlander key?
Call a mobile locksmith before you call the dealer. On a 2003 Highlander, the dealer needs to order the key, cut it, and program the transponder, and that process often means leaving your vehicle overnight or waiting on parts. The bill reflects all of that. With EZ Car Keyz, I come to you in Santee, cut the blade on site, and handle the transponder enrollment through the OBD port in the same visit. No tow, no appointment days out, no separate line items for cutting versus programming versus the fob. You pay way less than the dealer route for the same working result.
How much harder is all-keys-lost on a 2003 Highlander compared to just making a spare?
Are aftermarket fobs for the 2003 Highlander worth it, or should I stick with OEM?
My 2003 Highlander starts fine but the remote will not lock or unlock the doors. What is going on?
Can I program a replacement fob for my 2003 Highlander myself at home?
