Customer Reviews for Oxford Screamer Alarmed Disc Lock

Oxford Screamer Alarmed Disc Lock

Third time lucky

I have always found Oxford locks to be good quality, so may have just been unlucky with this one. The first lock I purchased was missing the allen key so I couldn't unwrap the battery to activate it. The second lock had the key, but when locked onto the bike and alarm set, started making a very odd, constant warbling noise. Third lock seems to be working alright, but I suppose time will tell.

Good lock, rubbish alarm

The lock itself seems quite good but the alarm would not work properly at all. Just made a random buzzing noise when I inserted the key. Returned it and bought a second one which worked well for 2 days and now the alarm is so quiet you can hardly hear it.

Questions and Answers

  • Will this fit any bike?

    May 29, 2018

    This is a universal product, but we cannot gaurentee that it will fit very bike. As long as the pin will fit in the hole in your disc, or through the disc carrier itself, it will be suitable.
