2001 Lexus LS Key Replacement

The 2001–2006 LS uses the same key setup, so everything on this page applies to those years too. The full picture is on the Lexus LS key guide.

2001 Lexus LS: key facts

Key type: Transponder chip key
Push-to-start: No
Transponder chip: 4D-68
Programming: OBD
All keys lost: We can originate new keys on site

LS430: vendor catalogs list the 4D-68 short high-security key (TOY50-PT) for the full 2001-2006 run; we still confirm from the key stamp or VIN on early cars.

What kind of key does a 2001 Lexus LS use?

The 2001 LS is a transponder car with a regular turn-key ignition. There is no push-to-start button on this year. The key carries a 4D-68 chip family, and that chip has to be recognized by the car before the engine will run. Cutting the blade alone is not enough.

The blade is a laser-cut high-security style, and the car also has a mechanical backup key. That matters for owners in a few ways. A plain hardware-store copy might turn the lock, but it will not start the car, because it has no chip. That is one of the most common problems we see listed for this model. Wear is the other one: a worn or chipped blade can stop turning the lock, and on high-mileage cars the ignition wafers themselves can wear down. If a key has started to feel gritty or hesitant, the problem may be the key, the ignition, or both, and it is worth looking at before the key fails completely.

Duplicate key or all keys lost: how does it differ on this car?

If you still have a working key, copying is the simpler path. For this setup the original key is needed to make the copy, so the best time to add a spare is before the last one goes missing or gets worn out. We cut the new blade, then program the chip to the car.

If every key is gone, it is still possible. All-keys-lost work on a 2001 LS is doable, and programming is done through the OBD port. Our data shows this year does not require NASTF SDRM registration for programming. It simply takes longer and involves more steps than a copy, because we start without a key to reference.

One working key: copy cut and chip programmed, usually the more economical route.
No working key: new key made from the car's information and programmed by OBD.
Worn blade on your only key: replace it now, before it stops turning and becomes an all-keys-lost job.

How we handle a 2001 LS key, step by step

The process is the same whether you come to our Westwood storefront at 10740 Wilshire Blvd or have one of our mobile vans come to the car.

Confirm the car: we check the year and model, and look at the key stamp or VIN so we cut and program the correct key.
Check what you have: a working key, a worn key, a non-chip copy, or nothing at all.
Cut the laser-cut blade to fit your locks and ignition, checking how the ignition turns while we are there.
Program the 4D-68 transponder to the car through the OBD port.
Test everything: start the engine, run the key in the door and ignition, and test any spare.

What affects the price of a 2001 Lexus LS key?

We do not quote numbers on a web page because the job decides the cost, not the badge on the car. These are the things that move it:

Copy or all keys lost: starting from a working key takes less work than starting from nothing.
How many keys you want: a spare made in the same visit is usually more economical than coming back later.
Condition of the ignition: if worn wafers are making the key hesitate, that repair is a separate item and we will tell you before we do it.
Where the car is: coming to the storefront is different from a mobile visit to wherever the car is parked.
Time of day: we answer the phone at (213) 577-1366 around the clock, and after-hours work is priced differently from daytime work.
Key stamp or VIN check: if the early-car details need confirming, we do that first so nothing is cut or bought wrong.

What we confirm by VIN, and why call us

One honest note. Vendor catalogs list the 4D-68 short high-security key, TOY50-PT, for the whole 2001 to 2006 LS430 run. The 4D-68 chip family is verified for your year, but on early cars we still check the key stamp or VIN before we cut or order anything. It is a quick step, and it keeps a wrong key from being made.

Wilshire Lock & Key has been in business since 1987, with a storefront in Westwood and mobile vans serving 140 cities across Los Angeles and Ventura counties. You deal with one company, not a dispatch middleman, and David, the owner and lead technician, oversees the work. California requires locksmith companies to hold a BSIS LCO license, and you should ask any locksmith for it, us included.

Frequently asked questions

Does a 2001 Lexus LS have a push-to-start key?

No. The 2001 LS uses a turn-key ignition with a 4D-68 transponder key. There is no push-to-start system on this year.

Can a hardware-store copy start my 2001 LS?

No. A copy without the transponder chip may turn the lock, but the car will not start. The chip has to be programmed to the car.

Can you make a key if I lost every key?

Yes. All-keys-lost is possible on this car. We program the new key through the OBD port. It takes more steps than a copy, but it does not require a dealer visit.

Do I need my original key to get a duplicate?

Yes, for a standard duplicate on this setup the original working key is needed. If you have no working key, we handle it as an all-keys-lost job instead.

My key is hard to turn. Is it the key or the ignition?

It can be either. Worn or chipped laser-cut blades are common, and so are worn ignition wafers on high-mileage cars. We check both so you do not replace the wrong part.

Is there a spare mechanical key for the 2001 LS?

Yes, the car has a mechanical backup key. Keep it somewhere safe, but remember a mechanical key alone will not start the engine.

How do you know you have the right key for my car?

The 4D-68 chip family is verified for this year, but we still check the key stamp or VIN on early cars before cutting or ordering. That confirms the exact key for your LS.
