You can purchase a lock and keys like mentioned before then you can try goo gone to get the gum off the bottom of the speedy. You can purchase Goo Gone at Target. Test a small area where there is gum on a qtip and rub it gently. I used the Goo Gone on the side of my Brazza wallet where it looked gray and my SA said it was glue and she gently tried earasing it with a pencil eraser but I can still see it so I tried the Goo Gone on a qtip and gently rubbed it on my wallet and it came out. DH sat on gum in the movie theatre and I used Goo Gone on his jeans as well. Hope this works. Let me know if it worked.
