how do you make the step lock gate expand?

i have a fisher price step lock gate and can't get it to expand the instructions don't include that part

i assume you mean the door lock seloniod? if so go to the dealer I've found that the aftermarket i.e. auto zone, advanced etc. parts are not very good, they are noisy and do not last very long

Try the new Cutters shockskin reciever cloves! 3 of my team mates wear them and they're super sticky yet decently padded and doesn't restrict movement at all!
