HO uncoupler

As I said in the pass, it has been many years since I played with my railroad, after about 20 years I uncrated it and now built a new layout, I put in the uncouplers and to my surprise after I bought some new caars the coupling don’t have the same little hooks or points that makes the uncoupler work , can someone help me out?

The "new " knuckle couplers that are included on today’s rolling stock
are magnetic couplers. They are uncoupled using an under the track magnet. Dave
