We just acquired an 05 Element. Now we've got three Honda's - The 05 Element an 01 Odyssey and an 09 Accord. With all these keys I was wondering if somehow I could use one key for two cars. The 01 is out of the picture for sharing keys, it's quite a bit different. But the Element and Accord keys are similar. I was thinking of getting one key cut with the 09 car on one side and 05 on the other. Getting the transponder for each vehicle on one key may be difficult. Does anyone know if the ignition reads one side or both sides of the key?
