Program lx key to start

[smltwnst100]

Just bought an aftermarket key, programmed buttons, does anyone know a way to program to start without device?

In the FAQ there is a posting that runs through most is not all the possible issues.

Programming a key

Ok, I found the programming sequence. My question is, if I try and mess up, will it mess up my current key? I was told by Sewell, I could possibly make my vehicle non functional

I believe that even in techstream they make it impossible to delete all keys. I highly doubt you could mess up your current working key's programming using the non-techstream sequence, and I have never heard/read of this happening to anyone. The only way I've heard to delete all keys is by flashing the ECU, and even then, the ECU goes into auto programming mode and registers the first three keys you insert.

Ok so I tried to program the key using brake/accelerater pedal and it didn't work

Anyone know the programming method for a 04 lx? Looked but haven't found anything

there are different routines depending on year - I think they are broken out on this webpage maintained by @RobRed

smltwnst100- I'm in need of an extra key as well. I've only been able to locate key shells no chip. Can you tell me where you purchased yours?

I got mine from 1010keys on eBay
"PRE-CUT" DIY PROGRAM 3 BUTTON FOB REMOTE KEY with RED BUTTON Listed models 03-P

It worked great from programming locks but haven't had any luck with starting. It says I can pay an additional $25 for code but haven't done so yet
