Question 1

What is the cheapest way to replace my 2000 Cadillac Eldorado key?

Accepted Answer

Call a mobile locksmith before you call the dealer. Dealers on late-90s and early-2000s GM vehicles tend to charge for the part, the labor, and sometimes a diagnostic fee on top, and they often need to order the fob if they don't stock it. With EZ Car Keyz, you're getting the fob and the programming done on site in one trip, for a fraction of what a dealer visit runs. If you still have your original key or fob, even a broken one, bring everything. The more I have to work with, the faster the job goes.

Question 2

How much more does all-keys-lost cost compared to adding a spare?

Accepted Answer

More. On the 2000 Eldorado, adding a spare when you have a working fob is a simpler process. All-keys-lost means the vehicle's security system has to be accessed and the key memory handled differently, which adds time and complexity. The gap in cost between "I have one working key" and "I have zero keys" is real. The single best thing you can do right now, if you're reading this with one fob in your hand, is get a second one made. It will cost you less today than it will the week you lose that last one.

Question 3

Are aftermarket fobs for the 2000 Eldorado cheaper, and do they actually work?

Accepted Answer

They can be cheaper upfront. For a vehicle this age, the fob hardware is a known quantity and aftermarket options exist. The issue owners run into is build quality on the shell and buttons. On a fob that's already 20-plus years old from the factory, the last thing you want is a replacement that starts falling apart in another year. We carry OEM-spec units verified for this vehicle so you're not rolling the dice on a fob that programs but then fails mechanically six months later. The programming side is the same either way. It's the long-term reliability where the difference shows up.

Question 4

My 2000 Eldorado fob worked fine yesterday and now the car won't respond to it at all. What happened?

Accepted Answer

A few things can cause that on these. First suspect is always the CR2032. Even a battery that's only a year old can drop below the threshold the receiver needs, especially in heat. California summer heat sitting in a parked car accelerates battery drain on these older fobs noticeably.

If a fresh CR2032 doesn't bring it back, the fob may have lost its pairing to the vehicle. This can happen if the battery died completely and stayed dead for a period, or if the fob got reset somehow. That's a programming job, not a hardware problem.

The third possibility is the fob itself. On a fob this age, internal contacts wear out. If you press a button and feel it click but nothing happens, that's usually the button contact, not the receiver in the car.

Question 5

Can I just buy a fob online and program it myself to my 2000 Eldorado?

Accepted Answer

There is an onboard programming procedure for adding fobs on some late-90s and early-2000s GM vehicles that involves the ignition and door locks, but whether it works reliably depends on the specific setup and whether the vehicle's security system cooperates. It also typically requires that you already have a working programmed fob in hand to initiate the sequence. If you're starting with zero working fobs, the onboard method won't get you there. A fob bought online is just the hardware. The programming still has to happen, one way or another.
