@jensus11 so you are using an older model BLTouch with a metal pin? Sinve version2.1 or so BLTouch comes with nylon pins. Or are you saying you nagnets are so strong it overpowers the BLTouch mechanism further up?
In the former case, you may be able to get a replacement nylon pin and it may work (or get a newer BLTouch with nylon pin). In the latter case you will need to consider another probe like klicky/euclid if you still want to probe the actual surface; or an inductive probe or scanning probe if you want to go touchless.
