Question 1

What is the least expensive way to replace a key for a 2000 Land Rover Discovery?

Accepted Answer

Call a mobile locksmith who knows older European vehicles before you call the dealer. The dealer path for a 2000 Discovery usually means scheduling time, potentially towing the vehicle to them, and paying separately for the key itself, the cut, and the programming labor. It adds up fast.

With us, the remote head key, the cut, and all programming are handled in one visit at your location in Ventura or Casitas Springs. No tow, no waiting days for a factory order, no separate line items for each piece of the job. Call for current pricing. The gap between what we charge and what a dealer quotes is significant.

Question 2

How much harder is all-keys-lost compared to adding a spare to a working key?

Accepted Answer

On the 2000 Discovery, the difference matters. If you still have one working key, adding a spare is a shorter job. The system already has a registered key in memory to anchor the process.

All-keys-lost means the vehicle has no working key at all. The immobilizer has to be reset, old key memory wiped, and new keys enrolled from zero. That takes more time and more tooling. It is doable on site, but it is the harder version of the job.

The practical advice: as soon as you get a replacement key made, have a spare cut and programmed at the same visit. On a vehicle this age, hunting down a second key later costs more than doing both at once right now.

Question 3

Do aftermarket keys work on the 2000 Discovery, or should I stick with OEM spec?

Accepted Answer

On a vehicle this age, the shell is the easy part. Discovery owners have had reasonable results swapping circuit boards from a known-good original fob into a new aftermarket housing when the original shell cracks or a button tab breaks. That works because you are keeping the original electronics.

Cheap aftermarket fobs with their own circuit boards are a different gamble. Reports from Discovery forums go both ways, but the consistent theme is that low-cost fobs sourced from generic online listings either program poorly, have short range, or stop communicating with the vehicle after a short time.

We carry OEM-spec keys verified for the 2000 Discovery. That means the electronics are built to the factory specification, the blade is cut correctly for your vehicle, and the whole unit is tested before I leave your driveway.

Question 4

My Discovery remote stopped locking and unlocking but the key still starts the car fine. Are those two systems separate?

Accepted Answer

Yes, they are independent. On the 2000 Discovery, the remote functions and the ignition system operate through different circuits. The key starting the car means the ignition side is intact. The remote buttons going dead usually points to the fob itself: dead or weak CR2032, corroded battery contacts, or a failed button membrane after years of use. Start with a fresh battery seated firmly. If the range comes back but is short, the contacts needed cleaning. If neither button does anything with a confirmed fresh cell, the fob electronics may have given out and the remote head key needs to be replaced and reprogrammed.

Question 5

Can I program a second key to my 2000 Discovery myself at home?

Accepted Answer

There are DIY sequences documented on Discovery forums, and some owners on older examples have reported limited success with ignition-based relearn procedures. However, results on the 2000 model are inconsistent enough that it is not a reliable method. The remote programming in particular tends to require either a working procedure with a confirmed working fob or a proper diagnostic tool to register the key correctly.

If you want to try a documented owner procedure you found in a forum thread, that is your call. But if it does not take, do not keep cycling through attempts. Repeated failed programming tries can complicate the job for a locksmith afterward. Better to call first and ask whether a DIY sequence is worth attempting on your specific vehicle before you try it.
