Does anyone know how to remove the roof rails from a 10 X5 M sport or X 5M (they have the same rails).

My GF hit the garage with my mountain bike on the rack this morning.
No damage to the bike or the bike rack, but it bent the roof rail on the car.
Luck there's no other damage to the car.

I found a rail in LA that I'll go and get today.

BUT, I need to know how to get the rail off to put the new rail on.

Any help any can give me I'd be very thankful for…
