Locked myself out: what to do step by step

Before calling a handyman, quickly review these options:

• Neighbour with a spare key - Do any relatives, a partner or a neighbour have a spare key? Call them before doing anything else.
• Building manager or flat owner - Residential buildings usually have a caretaker or janitor. During working hours, they will open the door for you or have access to a spare key.
• Key in the backpack or pocket - It may sound trivial, but check all pockets, your bag and jacket again. Keys are easier to lose than you think.
• Open window or balcony - if you live on the ground floor or first floor and have an open window, this route may also help. But beware, watch your height and safety.

If none of these options work, it is time to call a professional.

• Price quoted on site - A reputable handyman will quote a price before dispatch or at least provide a reasonable estimate. If they refuse to give a price over the phone, it is a warning sign.
• No invoice or receipt required - Every honest handyman issues a receipt. Without a receipt, you have no protection.
• Immediate pressure to replace the lock - some dishonest locksmiths intentionally damage the lock during opening and then force an unnecessary replacement at an exorbitant price.
