🔧 PRO TIP
The 2003 Impreza uses a separate remote and mechanical key setup, not a smart key or fob combo. The remote is FCC ID NHVWB1U711, part number 88036-XA010, running a CR2025 battery. The transponder lives inside the key head, not the remote. It runs Subaru's fixed-code immobilizer with a Philips ID 4D62 chip talking to the Body Integrated Unit. If the remote dies, the car still starts. If the transponder chip fails, it cranks but won't fire.

2003 Subaru Impreza Remote Replacement - Fast, Affordable & Professional

A guy near Hummingbird Trailhead in Simi Valley flagged me down, so to speak, through a referral. His 2003 Impreza had a key done by another locksmith about a week earlier. It started fine for the first few days, then one evening the engine cranked and cranked but wouldn't catch. Next morning it fired right up. By the following night, same thing. Dead crank, security light blinking on the dash.

He thought the car had a fuel pump issue. Took it to a mechanic. Mechanic found nothing wrong and told him to check the key.

I pulled out my VVDI2, read the transponder in his key, and there it was. The other locksmith had cloned a 4D60 chip instead of the correct 4D62 that Subaru's immobilizer expects. A close relative in the Philips 4D family, close enough to fool the Body Integrated Unit on initial registration, but the rolling encryption handshake drifts and eventually the BIU rejects it. That's the intermittent no-start.

Cut a new key on a correct ID 4D62 blank, programmed it to the BIU through the OBD port, and swapped his CR2025 in the NHVWB1U711 remote while I was at it since it was reading low. Tested lock, unlock, trunk, panic. All four buttons responded clean.

He'd already spent money on a mechanic visit that found nothing. The whole problem was the wrong chip inside a key that looked perfectly fine.

“Tim was GREAT. I honestly swear he must have had my keys made before he even showed up. The entire process was insanely fast, from the initial phone call to having the keys in my hand. No one will beat the pricing, efficiency, or outstanding service.”

“Locked out on a weekend night and everyone else wanted $300+. EZ Car Keyz sent Roman late at night for much less. He worked for over an hour and did not give up until the door opened. They even made a new key on the spot.”

Subaru Impreza Mobile Service FAQ

Real costs, no dealer surprises

I lost all my keys for my 2003 Impreza. Can you still make a new one?
Yep. All-keys-lost on the 2003 Impreza means working directly with the Body Integrated Unit, which is Subaru's combined security and body control module. I access the BIU through the OBD-II port, reset the immobilizer, and register a fresh ID 4D62 transponder key so the old missing keys are erased from memory. There's a mandatory security timer built into the procedure, usually around 15 to 20 minutes of wait time before the BIU accepts a new key. After that, cut the mechanical blade, program the NHVWB1U711 remote, and you're driving. The whole thing happens at your car, no tow needed.
Do I have to go to the Subaru dealer if I have no working keys?
How long does an all-keys-lost replacement take on a 2003 Impreza?
