I've recently acquired an original luggage rack complete with locks and a single key. I've read that these were allegedly made by Thule and consequently Thule keys can be bought as replacements. However the key I have has a four digit number 99xx, and an Internet search doesn't bring up any Thule keys numbered in this format. I happen to have a Thule roof rack of similar vintage and the keys for that are a different shape and numbered Nxxx.
Before I take the lock and key to Timpsons does anyone know if these keys can be bought on the Internet by number?
