Hi Eric, thanks for your interest, the lock is embedded number lock and it is secure. Yes, the wheels can rotate 360 degree and the material is Polypropylene plastic. For wheels rubber and plastic handle deteriorate and break off it will really depend of the usage of the luggage. It will best if you can store the luggage properly when not in use, store your luggage in a clean and dry area, away from direct sunlight and extreme temperatures. The warranty period for this luggage is 1 year. But it is only applicable for manufacture defect but not include wear and tear issue or misuse. Thank you
