I just set up a FOB and master key, for an 07LX without either. The fob you show is a HYQ 1512V. Try it but I doubt it will work.
All the ebay & Amazon sellers are showing these HYQ 1512V good for 03-07, some even say 98-07. They are wrong IMO.
I had to get Fob HYQ 12BBT for my 07LX (06-07 LC or LX). I found one that was listed as a refurbished, with short uncut key for $50.
I had a tough time doing the job, as I had two issues.
1) DTC for inop wireless receive. Found that dome lights were out, along with running broad lights and door open light on dash. As it turns out, all was due to a dome fuse RH J/Box. Replace the fuse and DTC cleared and all lights worked.
2) But still, I could not get new FOB (1512V) to work. So I grab my 06 LC fob and it worked. Pulled it apart and found it to be 12BBT fob.
06-07 is the 12BBT fob
@2001LC thank you for this post. If I'm reading this correctly, in order to program a new key there must be no DTCs to complete the programming? Thanks
