Surelock Homes provides an experienced and expert garage security service to home owners, landlords and local businesses. Our supply and fit service for up and over garage doors can also provide you with additional security measures. We can open any garage door even if the lock is faulty, jammed or the keys have been lost. Due to the wide range of stock that we carry we are usually able to replace your garage lock on our first visit. If you have just moved house or your keys are lost give us a call, we are here to help.

The standard up and over garage door can make an easy target for criminals as some garage doors are not very secure. We would recommend extra security as a good idea for these types of garage doors. We can for example; attach high security bolts to either side of most up and over garage doors. These bolts sit on the inside and are bolted through with 4 X bolts operated with a high security key and they will shoot a bolt approximately 2 inches into either side of the door frame. This is a neat, affordable, high garage security solution and additional keys can be cut as required, please ask when calling.

Most garage door lock replacements can easily be quoted over the phone so please call for a free no obligation quotation. The list of garage locks below are those we regularly supply to our Portsmouth customers, if there is a make not on the list don’t worry we will be able to get hold of it for you:

  • ERA
