Thank you so much for your response. The local hardware store here had the HD74, much to my happiness and surprise. Even more excellent is the fact that the blank key does indeed work on the newer Radrunner 2.

I'm going to get another blank just to have. It'll be nice to carry just one key around and not have to worry about losing the originals . I will also be a bit more proactive about making sure these don't get stolen, now knowing how easy it is to unlock.

Will the Ilco blank work for a newer RadRunner? We bought two in December 2021 and have been traveling with them on our RV. We lost the keys for one of them (key code F28), tried using the key from the other one (key code F05) and it worked to click the bike ?off? but now it won?t turn back on or even release the battery. I was hoping these were universal from what I?ve been reading but it doesn?t seem so.

I?m guess I can have a replacement key sent home but it would be a lot more convenient to walk into a hardware store and order a buy a working blank so we can use the bike the rest of the trip.

If the key from the other bike doesn?t work does that mean a blank also would not work?

Thanks in advance
