Ikea Shelf 'Keyed' Slot Router Bit?

[mwerner]

A while ago we bought an Ikea HAUGA Shelf/cupboard unit.
One of the tall end panels was faulty with the drilled holes and routed slots in the wrong place. Ikea replaced the whole unit without question but we've been left with the old faulty one which I'd now like to put to use.
I can re-drill most of the holes but the main shelves have some 'keyed' slots to accommodate some profiled plastic pegs (see photos attached) and wondering if anyone knows of an off-the-shelf router bit that would be able to cut the holes/slots for these.
Kind regards

Looks like you need a keyhole router bit. They are available in various sizes. The following link is just to show you what they look like.

It would need to fit the profile of the plastic peg shown in the first photo.

I've found an article that seems to reference this locking system (or similar one) but unfortunately no talk of router bits to replicate it: https://www.core77.com/posts/27726/...s-and-a-potential-end-to-particle-board-27726

Perhaps you need a beading bit?

Axcaliber Convex Multi-Bead Cutter

This cutter produces a very attractive triple beaded edge in one simple pass. Used with either the fence or without (self-guided). Stopping the moulding short creates a classic looking edge on shelving. Axcaliber router cutters are high precision...

No idea which size though, and I am only guessing.

Alternatively, you might be able to use cam dowels higher up (if one face is hidden).

Just drill hole large enough to accept peg and secure shelf with a couple of small L brackets .
