First of all, please check if the toy is fully charged if it is a rechargeable device. Switching on during active charging is not possible.
Some items have a key lock. You can find out if your toy has a key lock in the user manual or in the product description on our website.
Usually, you can deactivate the button lock by holding down the + and - buttons simultaneously for a few seconds and then starting the toy by pressing the + button.
Your toy is powered by batteries?
Then please check if they are really inserted the right way around. In rare cases, the + and - signs in the battery compartment are printed very faintly and are therefore difficult to see. Also, the cover of the battery compartment must be firmly in place and clicked into place.
