I now have 4 keys, 1 that came with the vehicle, 2 I got from my local ace hardware and 1 I ordered on ebay. The key I got with the vehicle was cut as a master (meaning it opened all doors and the glove box, the blade was the correct 'master' cut) but the transponder was programmed as the valet key. If you don't have a key that will lock and unlock the glove box I am not sure that you can have one made, maybe by getting the key code information but having someone copy the current key will not help if it currently does not lock/unlock the glovebox. You can still program that key as a master though, I think the master cut and master programming are 2 different things. 2 of my new keys came with the button fobs, but for some reason I am not able to program them to work. The one I got from ace i believe is the wrong frequency as the sticker inside says rx300 or something. I think they ordered the wrong key, the immobilizer transponder must have been correct but the fob frequency I don't think is. i got that key free so I don't mind the fob not working. The key I got from ebay said it was the correct frequency but I also could not get the fob programmed. I contacted the seller and they told me it wasn't the right one, even though everything seemed to match up on my end and the ad said 2001 lx470. I was able to program it to start the car but thats it. I was going to send it back but it was only $20 and I had already got it cut. Its also one of the newer style flip out rectangular keys, which I wanted, so I kept it and put the original key fob unit into that key, which still worked to lock and unlock the doors. The seller steered me to a new lexus oem key and told me I needed that one. Not sure why they think I need that one and theirs won't program when lots of other people have done it. The lexus key is $70 and the seller doesn't accept returns, so I have been reluctant to buy it and see if it works. I don't need 5 keys, especially if I can't program the fobs. So for now, 4 keys that start the car with 1 having working key fob is ok with me. I'd love to figure out why I can't seem to program another fob, but don't really want to throw more money at it. So until I figure out what the fob deal is, I will deal with what I've got. If anyone can shed light on that it would be much appreciated! I took my working fob apart to see if there were any distinguishing marks, but searching the numbers inside didn't seem to come up with anything that I could find. The fob inside has 60010 or something on the plastic, which is what the ebay seller used to find the key fob that will supposedly work, but I don't know if that is what I need or not.
On a side note, when programming the fob using the lock and unlock method while sitting inside the car you must make sure your lock actuators are working properly. If the door locks don't physically move all the way each time then it won't go into programming mode. My actuators stopped working fully after a few lock and unlock cycles so I had a helper sit in the passenger seat and while going through the cycles they would physically move the locks on the passenger side if they did not fully move while I did it on the drivers side. That allowed my vehicle to go into programming mode, but I still couldn't program any fobs besides the one I got with the car.
