I had the same problem. But if you look at the end caps there should be a serial number on them. If you take that number to a lock smith they will be able to cut you a new set for your roof rack. Mine cost me $5.00 CDN.
Hope this helps.
You want need a key to install the light bar. The hardest part is fishing the wire through the rubber grommet below the front left ( driver side ) roof corner light. The keys are also very similar E001- E006, I have E-003 on factory X-bars and E005 on factory light bar and I can use either key on both, but it is alittle tricky, you have to rack it in and out as u turn it and they will work. Good luck.
