My 2006 Element only has one key and remote so I'd like to get another one for it. I like the minimal bulk of the all-in-one key and so that sounds like a great idea. After having a look at some of the other threads about this mod, I saw a link posted to a website that lists the different systems used in Honda models
This thread (and a few others) talks about the Ridgeline keys being directly programmable starting in 2007 when the Element immobilizer system changes to Type 11 CAN "V" and matches those of the Ridgelines, according to that website. For Es prior to 2007, the threads indicate that directly programming the keys will not work because the immobilizer for Elements is a Type 3 while the Ridgeline is a Type 4 "V".
For example, this thread specifically about 2006 Elements attempting this mod
contains people saying that the Ridgeline keys were not able to be programmed by the dealership. But the posters do not say which year the key for the Ridgeline was from. Those posts were from 2009—the same year the Ridgeline keys switched to immobilizer Type 11 CAN "V".
BUT, that website I linked above lists the the immobilizer for a 2006 Element as a Type 4 "V". That seems to suggest that a chip from a 2003-2008 Accord/2005-2006 Odyssey/2006-2008 Pilot/2005-2008 Ridgeline should be directly programmable to work.
Am I misunderstanding the information on that website about the immobilizer systems? Is the information on the website is incorrect for 2006 Elements? Has anyone tried to directly program a key compatible with one of those models? If so, did it work?
If one of the keys from those other models is not directly programmable, and I understand correctly, to use the Ridgeline key I will need to:
1. Purchase a 2006 Element compatible key online or from the dealership;
2. Have the dealership program the chip in that key to my E;
3. Purchase a Ridgeline key either online or from the dealership and have it cut;
4. Remove the newly programmed chip from the 2006 Element key and place it into the Ridgeline key;
5. Program the remote.
