Vehicle Diagnostics


Our vehicle diagnostics service is backed up with almost 3 decades of experience in auto electronics.  Back before cars had networks built in to them (yes that's the CAN bit - Controller Area Network) we worked on the electrical systems of all major makes and models of vehicles

including plant and machinery  and the worst a vehicle could normally throw at us would be some faulty wiring, bad earthing or maybe a blown fuse or relay.  These days things are very different and modern vehicles ar packed full of high tech, high spec controllers that all communicate with each other

over the vehicles CAN network.  This means that checking fuses whilst still an important part of diagnosing faults, is now just the starting blocks of the race (or marathon) to find the fault.

Our state of the art diagnostic kit can diagnose almost any piece of equipment available from trucks to tractors , cars to combined harvesters and is mostly dealer level equipment normally reserved for manufacturers.

This enables us to quickly diagnose the problem and identify faulty components to allow us to get you back moving again because after all is said and done - time is money so the quicker we get you fixed up, the more money you save.

We can also tune the software on your equipment or car,van,truck,bike for more power /performance or economy using a process called Remapping.

We repair most types of dashboards and have the ability to correct mileage or hours on most electronic control units and dashboards (including plant equipment).

Call us now for advice (that bit is free).

Mileage Correction

Our Mileage Correction Service enables mileage or hours correction on almost any vehicle with a digital odometer or hour meter.

Mileage Correction can be carried out for a number of reasons.

Sometimes flat batteries cause the value on the mileage odometer or hour meter to display incorrect data or you may of just had a new instrument cluster or hour meter with 0 miles or hours on it and need it adjusting accordingly, or a secondhand cluster/meter and its reading too many miles/hours, then you will need our odometer/hours correction services.

Vehicle Immobiliser Repair / Removal


Call or text 07851 013015 for a quote.


As everybody who has experienced some kind of immobiliser failure in the past (or right now), Immobilisers are both a godsend and a curse all at the same time.  

They are invaluable at keeping your pride and joy safe from the hands of those who would wish to deprive you of it,

but they can also be the biggest PiTA (sorry couldn't help it) imaginable.  A faulty immobiliser may as well be a steel box with your vehicle locked inside of it.  

If it fails you're going nowhere. Failures can range from keys that get forgotten by the system to faults within the immobiliser code within the engine ECU (the brains),

to damaged circuitry as a result of the vehicle being jump started.


All of which result in one thing - You're vehicle will not start (and often won't even let you in).


Here at Tech Doctor Anglesey we offer a range of services from repair of the faulty component/s to removal of the code within the ECU or module that runs the immobiliser system.  

Why would you want to remove it?

Well that one is a matter of economics, an intermittent fault could take many hours to find at a workshop

and with workshop rates being in the region of £30-£50 per hour it soon mounts up.

Compare this with our immobiliser off service where for example a Volkswagen Audi group vehicle costs £100

and can even be done mail order with our quick turnaround exchange service.

You soon realise it's often far cheaper to remove it than it would be to fix it.

Whichever way you choose to go with it give us a call on 07851 013015 and we will talk you through your options.

Key Programming

Call now on 07851 013015 for a Quote


Lost keys or keys that no longer start your vehicle

You may lose your key whilst you're on holiday or just as a matter of daily life but the end result is the same,

you either cannot get in to your vehicle or if it's already unlocked you won't be able to start

it to go on your way.  Either way it's going to ruin your day (and possibly your holiday).  

Here at Tech Doctor Anglesey we can provide new keys and program them into your vehicles security system

at a fraction of the cost of having your vehicle returned to your main dealer for them to do the same.

 Our specialist equipment will allow us to gain entry to most vehicles without damage and will then allow us to both

read the existing physical key data and to allow a new one to be cut, as well as allow us to remove the old lost key data (if required - see below)

and program in the new key data.

All as quickly as possible and with the minimum amount of fuss to get you back moving again.


Programming out old lost keys 

Key programming is an essential part of your vehicles security system and is often overlooked.  

Why would you overlook it? Well it's that age old saying if it aint broke don't try to fix it!!

Which for the most part is true, but if you've recently purchased a second hand car and only received one key with it

you are potentially at risk from someone taking it away with any of the spare keys which have been programmed over the cars lifetime

(up to 9 on some vehicles).  

A main dealer when they program a new key to your car will often leave the old ones programmed in just in case you find it tucked away at the back of your kitchen drawer etc...

This can then leave all those missing keys with potential access to your vehicle and also with the ability to drive it away without setting any factory fitted alarm systems off.  

Here at Tech Doctor Anglesey we can analyse your vehicle security system and with access to all the known keys (ie all the ones you got with it)

we can then remove all the old keys that are programmed into your vehicle PERMANENTLY.  

Once programmed out they will only be able to try to physically unlock the vehicle which in most cases will fail and set the alarm system off.


Even if they manage to gain entry to the vehicle they most certainly won't be able to start it

as the security systems immobiliser system will no longer recognise the chip hidden within the key.

White goods aren't white any more

With the introduction of Tech into our kitchens traditional white are no longer white and in most cases are no longer traditional.  Ok so they may still wash your clothes or keep your food cool but these days the modern washing machine weighs your clothes to see how much water it needs to wash them and sometimes will even analyse them to see what sort of temperature or detergent strength is needed.  Gone are the old twin tub days but this leaves us ever more in the hands of our tech as if something should go wrong it's no longer a case of a simple fix swapping out a broken belt (most are direct drive now).   At Tech Doctor we try to keep ahead of the curve so we are more than capable of tackling your no longer white goods woes.  Give us a call and let us take on your troublesome kit (we know you won't be disappointed).[...]
