  • Replacement Key for N091 Lock Core on Karrite Cargo Box
    The lock core on your Karrite Cargo Box reads N091. For the correct replacement key you just need part # THKEYN091. This includes 1 key so I recommend ordering a couple so you can have a spare on hand.

  • Replacement Key for Thule Adventurer Roof Mounted Cargo Box
    Simple fix! Just order a replacement key. Next to the key slot on the lock cylinder will be a key number engraved into the cylinder. It'll be the letter N followed by 3 digits. For example, if the lock has 'N030' engraved on it, you'd need replacement key, part # THKEYN030. Simply substitute your 3 digits for the '030', and type that in the search box on our website's home page to get the correct key. I've provided a photo showing where to find the key number.

  • How to Lock Thule Adventurer Cargo Box With Missing Lock Barrels
    Although you have the lock core, you are missing the lock cylinder or barrel assembly it would install into. Unfortunately, Thule doesn't offer this as a replacement part. To be honest, your best bet would be to get a couple of lock hasps like # ML702D and padlocks like # 141T.

  • Replacement Locks and Keys for Thule Ski Box with Key Broken Off Inside Lock Cylinder
    With a key broken off inside the lock, your only option is to drill out the lock and replace the core. For the replacement cores and keys for the matching set, I recommend the Thule One-Key System Lock Cylinders - Qty 2 # TH450200. With the key broken inside the lock, the master key won't work, so carefully drilling or calling a locksmith to drill for you are the only options. You may be able to drill into the key directly enough to get a bite so you can pull the broken key out and...

  • Will Swagman Cable Lock Fit Thule Threaded Hitch Pin for a Thule Bike Rack on a 2011 Buick Enclave
    Manufacturers make their threaded hitch pins and locks unique so that they can only be used with their products so you cannot use a Swagman lock in a Thule bike rack. The correct lock for a Thule bike rack is # THSTL2. You can also get Thule cable lock # TH538XT and then add Thule One-Key System Lock Cylinders, # TH450200, to key the hitch and cable locks alike to use 1 key for both locks. I have included a video review of the Thule lock for you.

  • Replacement Lock Core For Thule Evolution Roof Cargo Box
    The lock is not an item that is offered by Thule. If you have the lock and just need a new lock core you can order part # TH450200. This comes with two lock cores and two keys. Since this roof box is no longer available I cannot say it will definitely work with your crossbars. The best way to find out is to do a trial fit before ordering the replacement lock cores.

  • Troubleshooting 2nd Hand Cargo Box Locked With No Keys
    On your second hand cargo box, there may be a number on the lock cylinder. If so, see if we have a replacement key using part THKEYN_ _ _ . For instance if the lock core reads 009, then you will use # THKEYN009 as the replacement key. If there is not a replacement key available or the lock core doesn't have a number, you may need to drill out the current lock and use a replacement like the Thule One-Key System Lock Cylinders - Qty 2 # TH450200 or the other style of lock # SR03807....

  • Availability of Replacement Thule Lock Cylinders to Match an Existing Key
    You can order Thule lock cylinders to fit existing keys as long as the key number is a 4 character code that starts with N. For example # THLOCKN011 which is the correct replacement for key N011. Replacement cylinders can get a little pricey depending on how many you need so it might be more economical to just order all new lock cylinders with keys and replace the ones you have. Part # TH450200 is a pair of cylinders and keys.

  • Tips for Removing Damaged Lock Core of Sears Cargo Box with Stuck Key

  • Locks for a Thule Frontier ES Cargo Box
    The cargo box itself can be locked which would prevent anyone from opening and thus removing the box.
