2001 Chrysler LHS
Key Replacement - Save vs Dealer in San Diego

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

More involved, yes. When you still have a working key, adding a second one is a relatively quick programming job. When every key is gone, the immobilizer has to be accessed to extract the security data and clear the existing key memory before any new key can be registered. That process takes longer and requires more from the equipment.

Q: Are aftermarket transponder keys cheaper and do they actually work on a 2001 LHS?

Some work, some don't. The problem with buying a key blank off Amazon for a late-90s or early-2000s Chrysler is that the transponder chip inside has to be the right type and has to accept programming for your system. A blank that looks correct and fits the ignition can still refuse to program if the chip spec is off. Locksmiths who work these vehicles regularly will tell you they've seen plenty of cheap blanks that simply won't take.

Q: My 2001 LHS cranks fine but dies immediately every time. Is that the transponder?

That exact symptom - cranks, fires briefly, then shuts off - is the immobilizer doing its job. It means the engine management system got a start signal but the security system didn't recognize the key's transponder, so it cut the engine. Could be a key that was never programmed, a key programmed to a different vehicle, or a key with a damaged chip.

Q: Can I program a replacement transponder key for a 2001 Chrysler LHS myself at home?

There is no owner-accessible add-a-key sequence on the 2001 LHS the way some older vehicles have. Some Chrysler products from this era do have an onboard relearn that works if you already have two working programmed keys, but if you're down to one key or zero, that option is off the table. Programming from scratch or all-keys-lost both require a tool that can communicate with the immobilizer through the diagnostic port. It's not a DIY job without that equipment.

2001 Chrysler LHS Transponder Key Replacement - Fast, Affordable & Professional

I got a call from someone up in Ramona Highlands on a Tuesday morning. He had a 2001 Chrysler LHS sitting in his driveway, wouldn't start.

He'd had a spare key cut at a hardware store months earlier, and when his original finally wore out, he grabbed the copy and tried to use it. Turned the key, engine cranked, fired up for about a second, and died. Tried it again. Same thing. He thought the car had a fuel problem or maybe the battery was going.

It wasn't either of those things.

I pulled up to his place and he handed me the hardware store copy. Transponder chip inside was either blank or incompatible - either way, the immobilizer saw the wrong signal and shut the engine down right after startup. Classic pattern on these late-model LHS keys. The car was fine. The key was the problem.

I had a compatible replacement with me. Cut the blade to match his lock, programmed the transponder on site through the diagnostic port, turned the key, and the car started and stayed running. He stood there for a second watching the idle settle and said he'd been convinced it was something mechanical.

He mentioned the dealer had quoted him a wait of several days just to get it looked at. I was done in under an hour, in his driveway, for a fraction of what that visit would have cost him. The hardware store copy is still sitting on his workbench somewhere, probably.

Chrysler LHS Mobile Service FAQ

Real costs, no dealer surprises

What is the cheapest way to replace a key for a 2001 Chrysler LHS?▼

Call a mobile locksmith before you call the dealer. The 2001 LHS uses a transponder key, so replacement isn't just cutting metal - the chip inside the key head has to be programmed to your specific vehicle. Dealers charge for the key, the programming, and sometimes a diagnostic fee on top of that. With EZ Car Keyz, you get the key cut to your vehicle and programmed on site, no tow required, no appointment, no separate line items.
