The HIDE safety key is designed to operate with the HIDE cover system. With the safety key correctly stored in a safe location away from children, the cover cannot be opened and is very safe. Removal of the lid can only be completed with the use of the HIDE safety key. If you have purchased a HIDE Kit and lost your key, you may buy a replacement key from your HIDE supplier with proof of purchase. If your key becomes faulty or breaks under warranty, we will replace it free of charge. Take the broken key to your supplier with proof and date of purchase.
