Recently my speedpass stopped working as I described in a prior posting.The nice folks at Speedpass sent me a replacement for the broken one and my others too. I was surprised to find that the Speedpass had a battery in it and still wonder why they didn’t just tell me to go to Radio Shack and get a replacement battery. I will call them today and give them the serial numbers on the old Speedpasses so they can’t be used. The speedpass from one of my motorcycles (picture of card tag on Harley) had the serial number worn off and so I decided to destroy it. I was really curious to see what was inside of it anyway. After a half hour I would have to describe the Speedpass as indestructible! It finally took a pneumatic saw to peel back the electronics inside. Fairly simple — in addition to the battery, there is an antenna, a small circuit board with one electronic element on it. Built to withstand nuclear attack. Here is a picture of the remains.
