Locksmithscan be funny. Some are awesome at delivering quality with good value for money, while others will rip you off whilst doing a half hearted job. Some also do a great job, but then hit you with a totally unfinished sum at the end of the job. All this can be avoided if you do your homework and prepare some questions and questions beforehand. This is especially important for larger projects like whole security system installations, and commercial projects that require a bit more funding and logistics. For emergency callouts and similar jobs it is a bit harder, as you need a service quickly, and have less time to sit and think.
Firstly, you will want to know an estimate. This is basically an estimation of what it will cost to install the system. It is important to request a total cost. This will include time and labor, and the cost of each piece of equipment being used in the system installation. This way you will not be unaware of any hidden costs or things you think you should not be charged for. Secondly, it is essential to ask how long it will take. If you know a time scale, you can plan around it, and also make sure that locksmiths are not taking you for a ride by spreading the work over months and months in order to get more cash.
Make sure you ring around several places for estimates and time scales. How do you know you are getting value for money if you only contact one company? Look up reputable companies with positive experiences and testimonials on the site or phonebook where they advertise. This way you know you are dealing with real professionals. Make sure you contact locksmiths by phone, this means that they are willing to talk as a real person, and not through some contact me form on a website.
