How much does it cost for installation only?

  • I only install car alarm systems that I sell and recommend.
  • If you’ve purchased a car alarm elsewhere, then get them to install it for you.
  • If they don’t provide an installation service, then avoid them. They don’t run a legitimate vehicle security business.

Why deal with the same business for both supply and installation?

  • They will be familiar with the car alarm systems that they deal with on a regular basis.
  • There should be no disputes about the product or installation if something does not work. In other words, it’s simple to fix should there be a warranty issue.
  • You are helping to weed out box sellers who I have very little respect for. They have no passion for cars, let alone any technical knowledge and skills. 
  • You should get better service.

  • Pricing is decided on what parts are required and how long the installation should take.

Does mobile car alarm installation cost more?

No – I charge the same price for car alarm installs at my workshop as I do if I am coming to you.

Installation & Service Questions

Can I install my own car alarm?

  • If you are competent with vehicle electrics, there is nothing stopping you from installing your own alarm.
  • Note: I don’t supply car alarms without installation, so you’ll need to look elsewhere if you wish to do this.

How long does a car alarm take to install?

  • Typically 3 to 6 hours, but it really depends on what vehicle you own and what alarm system is being installed. It’s not uncommon for me tp spend 2 days on an alarm installation.
  • If it is going to be over a days work, then I’ll ask you to drop the car off with me and collect it the next day.

Are there additional costs to installing alarms into new vehicles?

  • No – If the vehicle is new and needs some development work, I generally don’t charge more, especially if it’s going to be a popular model. 
  • Note: I will need more time with the vehicle.

Practical Concerns

Can car alarms be transferred to a new vehicle?

  • That depends if the alarm is suitable for the new vehicle – if so, then yes it can.
  • When removing an alarm, holes for sensors and LEDs may be left exposed.

Will getting a car alarm installed void the vehicle warranty?

  • No, I install alarms for many car dealers and have never had an issue.
  • The warranty can’t be voided because you’ve added an accessory: You should be covered under the Consumer Guarantees Act 1993.
  • If you have any doubts, check with the dealership and get it in writing before going ahead.
  • The warranty is between you and the car dealership.
