Replace kitchen front on older Ikea Rationell drawer

Hey Ikea fans,

I am new here, because I am desperate, and hope for your help.
I bought a used Faktum base cabinet (40 cm) with three drawers – and therefore without any instructions.
My plan was to replace the fronts on the drawers with new ones.
With the last generation, before Faktum was discontinued, I can do that, but these drawers seem older (and are also heavier) and apparently I am not wise enough to remove the front!?!

To remove the front of the shallow drawer, you have to push a small metal thing up on the side with a screwdriver and it comes off... but I can’t do that with the deep drawers, because the rods are still there... and they seem to be firmly glued/screwed to the front.
I can’t get any further on the back of the drawer either...

Can someone help me?
I did take photos so you can see which "model" of drawers I have, but I can’t insert them here.

I’m looking forward to support and hope it was okay to create this new topic, I didn’t find anything specifically about this type of drawer...

Best regards
Rebecca

Hello,

IKEA expert, thank you! finally, finally, finally I have the solution (and apparently always searched on YouTube under the wrong terms) and have already dismantled one rod for testing (the rest will follow). I’m dancing with joy and am even happier now that this forum exists. Thanks again and have a wonderful weekend!!!! Best regards Rebecca

A dance of joy - then the video was really worth it
Which terms do I need to add so that the video is better found on YouTube?

I have always searched for "Rationell Auszug (tief) Front wechseln (abmontieren)" or similar. "Reling" never occurred to me. I also didn’t know why it was stuck and where I had to start. Your video only refers to the rod, so the title fits. I just searched more broadly and simply couldn’t find anything ... Thanks again, anyway! And wishing you a good week Rebecca
