Emergency 2003 Land Rover Discovery key fob made from scratch by EZ Car Keyz Ventura CA
🔧 PRO TIP
The 2003 Discovery II uses a Lucas/NNN transponder system with an ID13 (Megamos 13) fixed-code chip inside the remote head key, part number CWE100710. That chip talks to the Body Control Unit (BeCM), not a separate immobilizer module. If your CR2032 dies, the remote buttons go dead but the transponder still starts the car because it is passive. Don't panic and call a tow. Just put the key in the ignition and turn it. The immobilizer side runs without battery power.

2003 Land Rover Discovery Remote Head Key Replacement - Fast, Affordable & Professional

Got a call from over in the Montalvo neighborhood in Ventura. Guy had a 2003 Discovery II sitting in his driveway, both keys gone. One lost at the beach months ago, the other went through the wash and quit working entirely. He said the dealer told him the car had to be towed in, and that they might need to replace the BeCM depending on how the security reset went. Multi-week timeline.

He sounded tired when he called. Not angry, just done with it.

I drove out, got the door open without damage, and decoded the lock on site. Cut a fresh CWE100710 remote head key on my portable machine right on his driveway. Then I connected to the OBD-II port under the dash and ran the all-keys-lost procedure through the BeCM, which on the Discovery II handles both the immobilizer and the remote central locking.

Programmed the ID13 transponder, synced the two-button remote at 315 MHz, and tested the full loop: ignition start, remote lock, remote unlock, walk-away range check. Cut and programmed a spare while I was there because on these trucks, getting a second key made while the system is already open saves a headache later.

He stood there watching the whole thing and at the end just said, "That's it?" That is the reaction I like.

Whole job, driveway, Montalvo neighborhood, fraction of what the dealer quoted and no tow truck involved.

“A+ service at an even better price. Tim was a lifesaver. I lost my original and only key for my Audi and he was willing to come to my location at 8pm the same day. He worked fast, communicated clearly, and made sure everything worked before leaving.”

“My Chevy key snapped while I was running errands in North Oxnard. He removed the broken piece from the ignition, cut a new blade, programmed the transponder, and tested everything thoroughly. The whole job was smooth and professional. Best automotive locksmith I have used.”

Land Rover Discovery Mobile Service FAQ

Real costs, no dealer surprises

What is the cheapest way to replace my 2003 Land Rover Discovery key?
Call a mobile locksmith who works on European vehicles before you call the dealer. The dealer route on a Discovery II means towing it in, ordering a CWE100710 blank, and paying shop time for the BeCM programming. That adds up fast, and the wait can stretch to weeks if they have to order the key. I come to your location in Ventura, cut and program the remote head key on site, and the whole thing runs a fraction of what the dealer wants. No tow, no drop-off appointment, no separate line items for the fob, blade, programming, and diagnostics.
How much more does all-keys-lost cost compared to just adding a spare?
Do aftermarket keys work on the 2003 Discovery II?
My Discovery II key turns but the engine cranks and won't start. Is it the immobilizer?
Can I program a new Discovery II key myself with a key-turn sequence?
