Smart card 2015 LX570 (1 Viewer)

[SgtMoonracer]

Does anybody have any tips on programming a smart card for a '15 LX? I purchased a refurbished smart card from UHS Hardware that is advertised to be compatible:

2008-2016 Lexus / Smart Card Key / PN: 89904-50642 / HYQ14ABB (OEM) - https://www.uhs-hardware.com/products/2008-2016-lexus-smart-card-key-pn-89904-50642-hyq14abb-oem

UHS Hardware's "tech support" (such as it is), are no help at all, but tell me that the refurbishment includes wiping the card, and this should allow it to be programmed. I get through the entire programming sequence in Techstream, and it tells me it cannot be programmed. I have four key slots available out of the original seven, and I tried it with the battery provided in the sale and a freshly-bought one in case the provided battery was low in power.

UHS tells me they "really" only sell to locksmiths, and normally don't accept returns from individuals, but I haven't quite decided to fight that battle yet. I just want to get the thing working. My local Lexus dealership's service department is quite lacking in anything but recall work, and I'd like to avoid them (and a programming fee) if at all possible.

Thoughts?

You may have the wrong year key. The same key definitely does not work on the 2008 through 16 model. Cross reference the p/n here and lexus parts to confirm.

If it is compatible, it may not actually be unlocked.

The numbers on the card don't seem to be a standard Lexus part number. I tried to attach a photo but it's too large. The embossing is:

05019/POSTEL/2007
2361
FCC ID HYQ14ABB
IC: 1551A-14ABB
DENSO


My Google-fu only pulls up a couple of hits on the first line, three of which are out of Hungary, and the fourth shows compatibility with 2007-2011, but I can't access the web link.

There is an eBay auction ongoing, Unlocked Virgin OEM Lexus Smart Card Key HYQ14ABB | eBay - https://www.ebay.com/itm/Unlocked-Virgin-OEM-Lexus-Smart-Card-Key-HYQ14ABB/332314622189?ssPageName=STRK%3AMEBIDX%3AIT that shows the same card that I have that says it's compatible.

Maybe mine is just not unlocked.

It appears to be the correct card. Looks like the shop you ordered charges a 25% restocking fee. I'd let them know it is not unlocked and ask for a replacement or refund waiving restock charges (or call cc and do a chargeback for a defective product).

There is an ebay seller that will unlock for about $20.

I have used them twice with success.

I'd only buy one of these used if it was really cheap, due to hassles like this. Good luck.

I had issues programming a Lexus key to my 2013 LC. It would go all they way through the process but I wouldn't get the program confirmation beep at the end when you place the key on the passenger seat. I replaced the battery a couple time with the same results. I even tested all the keyless entry sensors using TechStream thinking one was bad. In the end it was the battery. The voltage on the first few batteries I was using was just a little lower than the one that actually worked. I assume the LX process is the same as the LC.

If you are 100% sure you have good batteries, my guess is that the card is bad or it is not actually unlocked.

Just an update if anyone's following. I made the 30-mile round trip to the Lexus dealer today. They couldn't program it either. The guy said he did not have the capability to unlock the card, and he speculated the card was either locked, or was the wrong card. Since I seem to have established the card is correct, I don't think UHS Hardware unlocked it, or it's just a bad card. The dealership also could not cut the key that fits in the card that I purchased separately from an on-line Lexus dealer.

The tech at Lexus gave me the number of a local locksmith he thought might be able to unlock the card. He couldn't do it either; he said he didn't have the software. I've tried multiple, well-known locksmiths in the area, but no one has the ability to program or unlock the card.

I checked the battery with a multimeter, and the new batteries seemed to be just a bit over 3 volts. The one included with the card from UHS did not register on the meter.

UHS Hardware did agree to take the card back and sent an RMA number. We'll see if they try to charge a restocking fee.

Back to square one.

There is an ebay locksmith that unlocks for under $20. A return is probably your best option.
