I recently purchased a 2002 LX 470. It only had one master and one valet key, so I figured it would be a good idea to get some spares. Local locksmiths quoted $160 to cut/program a key. I didn't like that price. Then I saw a post by @katit for photo-cut keys on ebay. It was $35 and they fit perfectly. I used my current master key to program the two new keys following the instructions in this thread (from FAQs). Finally, I needed to program the fobs to lock/unlock the doors. The instructions provided from the ebay purchase did not work. The thread titled "Door locks programming" on FAQs seemed to be just for programing the locks to lock when shifting to park (let me know if I missed something...), not to program the fobs to work. After a lot of experimenting with the instructions I was provided with the keys, with various threads on here, and with youtube videos, I was able to program the fobs. Here is the sequence I used:
A few notes:
Attached are photos of the instructions the ebay seller provided me, for reference.
- Lock all doors
- Using driver's door MANUAL lock lever, UNLOCK and OPEN driver's door
- Insert key into the ignition (do not turn) and then remove the key
- Using driver's door MANUAL lock lever, LOCK and UNLOCK door 5 times
- Close the door, then open the door
- Using driver's door MANUAL lock lever, LOCK and UNLOCK door 5 times
- Insert key into ignition and turn to ON then OFF once, the remove key
- The driver's door will now lock and unlock itself 5 times, signaling it is in programming mode.
- Simultaneously press and release the LOCK and UNLOCK buttons on the remote you want to program
- Press and hold the LOCK button on the remote you want to program for about 2 seconds until you hear the locks lock and unlock. This is a confirmation that it worked. If it locks and unlocks twice, the programming has failed.
- Repeat steps 9-10 for each additional key that you want to program.
- Close the driver's door or insert the key into the ignition to exit programming mode
A few notes:
- I had to do this procedure with my already-programmed key first, and then repeat steps 9-10 with the additional keys after.
- Some places say you need to perform steps 9-10 outside of the car. That didn't work for me. Inside the car worked.
- Some places say you need to hold the buttons in step 9 for 1.5 seconds. That didn't work for me. I had to press them once and release, then hold in step 10 for 1-2 seconds until I saw/heard the locks cycle.
- If you go through steps 1-8 and then mess up step 10, I think it deletes the programming. On one of my earlier attempts I ended up wiping the programming on my initial key. Thankfully I was able to figure out the correct sequence later and restore it.
- Some places say to go slowly, but I did everything quickly and it was fine.
