★★★★★ Professional and very friendly service. Well trained staff on the phone and amazingly qualified locksmith, (despite his young age). My dad was well impressed and even shook his hand for doing such a great job!

Help, I locked myself out!

What should I do when I have locked myself out? Or when I have lost my keys? In case of lock-out, for example, if a door has slammed on you due to wind, or you just left your keys on the inside of the door or on the table, we can get you back into your house without damaging locks. In about 90% of cases there will be no damage to locks whatsoever. In rare cases we may need to drill and replace a cylinder or lock. We can replace your cylinder immediately and if necessary we can replace it for a cylinder that fits the same key you use on other doors. If your cylinders have the same profile, you will be able to open all your doors with a single key! In addition, we can implement an upgrade to your security and provide SKG*** certified high quality cylinders. We also provide registered cylinders with keys that are patented to prevent copying. You will be issued a key master card that you can use to order duplicate keys.

No call-out fees: A-keys | Slotenmaker Den Haag!


We only charge call out fees in very specific circumstances.* We maintain transparent ‘all-in’ prices for all goods and services. We always give you an estimate based on our assesment of your situation and our estimates cover everything from call-out, to work, materials and VAT (21%). We will never charge you extra for nights, weekends or holidays!


Payment: how will I be billed by A-keys | Slotenmaker The Hague?

If you have locked yourself out or experienced some other emergency with locks and keys you probably do not have a wallet or cash on you. Our technicians carry cash terminals that will enable you to pay by bank or credit card. Unless agreed otherwise prior to a call-out we will expect customers to pay us directly, as soon as work has been completed. You can also pay cash or transfer money using your banking app, as long as we are able to establish that payment has been received. As soon as we have your payment you will receive a receipt that includes all relevant information including our adress details. We can transfer receipts and invoices to you by e-mail or text message. The recipt is your digital warrantee and is valid for 5 years from date of issue! If you require a detailed invoice please notify the technician.

Pay later: is this an option?

In exceptional circumstances A-keys | Slotenmaker Den Haag can agree to invoice you later. Customers who are unable to pay immediately will need to clear the method of payment with the technician prior to making an appointment. A technician may ask for a down payment. Customers have no right to pay later. Unfortunately, our experience with invoicing is that delays in payment involve a lot of extra time and many customers end up paying us much later than stipulated in our terms and conditions (14 days Max).


5 year warrantee on goods & services

We exclusively work with the best quality materials available.* This way we avoid a lot of unnnecessary complications and ensure that our materials —locks, cylinders, keys and other security fittings — work properly for many years and require minimal to no servicing. If you do experience any problems with any security materials provided by us, we will replace it free of charge. As far as possible we do this immediately. A-keys | Slotenmaker Den Haag (SDH) guarantees high quality materials and workmanship!

In a few rare cases we will service or provide materials that have not been certified according to the modern SKG standards. For example, if you have an old or antique lock on your door and do not want to replace it, we can service it, or make improvements, but it will not be certified and you may need to check this with your insurance policy. Our technicians will inform you if this is the case.

How much does it cost to open or replace a cylinder or lock?

A normal emergency dooropening does not involve damage to doors or locks. In and around Den Haag we charge ± €85.- including VAT (21%). This is the standard price for opening a door as long as we do not need to drill. (90% of cases). If you take into account the price of publicity, websites, running the business, tax, insurance and VAT, this is a minimum charge and anyone claiming to work for less is likely to be a fraud.


Warning! Prices may increase if we need to drill or replace a lock or cylinder. These 'unexpected' costs are difficult to predict before we have inspected the situation on location. Our technicians will always inform you of any extra costs before they start work and they do not deliberately damage a cylinder or lock to increase their bills! In all cases, we discuss any out of the ordinary charges with our technicians to prevent them overcharging customers and we only employ people we trust to maintain our reputation for integrity.


iZettle PIN & BANK

You may pay us using bank or creditcards. Our technicians carry portable payment terminals.

Using our iZettle card reader terminal you can pay on the doorstep. iZettle PIN are completely secure and offer the comfort of direct payment.


Upon completion of your transaction you receive a receipt by e-mail or text message straight to your mobile phone.

You can also use a variety of apps to transfer money including Tikkie which is developed by ABN AMRO bank. You can download the app here: TIKKIE.


In principle we expect all customers to pay as soon as work has been completed.


Cash payment is welcome and you will be provided with a receipt and / or a digital invoice should you require one.

Caution! Locksmiths who demand high fees and cash payment may be frauds and youare not obliged to pay cash for any transaction! In some instances it may be practical for a technician to request cash, particularly if we happen to be short on cash, but it is not obligatory.


Digital invoices are submitted once every couple of days and you should receive yours on average not more than 3-4 days after payment. 


In exceptional cases and only upon prior agreement we will invoice you so you can pay later. This is on condition that:


  • You are already a customer in our system

  • We have your details in an email, and

  • We are able to establish your details are still up to date
