Is having 2 kids seats attached to your bike cool? No, not really! I had 1 Yepp mini locking seat on my handle bars that we lost the tubular key to. If you have had this problem you might call it a circle lock. We then bought a bigger rear mount Yepp Maxi which is why I had two. After searching and calling the manufacturer I decided to call TG to drill out the lock to get it off. What a solid guy TG is; affordable (he gave me the lowest quote out of 5 locksmiths),highly skilled, professional and fast! I called him Wednesday afternoon and he promptly showed up at my house a 2:30 at our scheduled time. He did a clean job and we removed the seat (he even helped me with the Allen bolts) within 10 minutes. TG is now my go to guy for any lock needs.
