champion Dave, Caravanner From Warwickshire two red stars [Online] Posted 27 January 2012 by Dave Quote | Report I've received an email from Alko advertising the fact that they are now selling the wheel inserts seperately. This means if you change your caravan you can keep your current lock and registration and get a new insert for £92. See below for quote from Alko and website. Should help reduce costs when changing your 'van. If you own an AL-KO Secure Wheel Lock Kit and have purchased a new caravan recently, we have some great money saving news for you! The alloy wheel specific inserts can now be purchased as a separate item with prices starting from £92.00 including free UK delivery. Simply purchase the specific insert to suit your new vehicle and keep your existing barrel lock, keys, locking bolt and socket. If your lock is already registered with us, then all we will need is the new caravan details to update your registration details. http://shop.al-ko.co.uk/sections/secure-wheel-inserts.html Post liked!
