🔍 YOUR WARNING LIGHT DESERVES A REAL ANSWER.

A generic code reader tells you what. Dealer-level diagnostics tell you why.

That difference matters. Generic tools flag a fault code and stop there. At TCM Autolocks, we connect with the same manufacturer software your dealer uses — Ford FDRS, VW ODIS, BMW ISTA — so we can dig deeper, test live data, and pinpoint the actual cause, not just the symptom.

Here's what that means for you:

✅ Accurate fault finding, first time
✅ Module coding and programming on-site
✅ ECU diagnostics without the dealership wait
✅ Mobile service. We come to your home or workplace
✅ Covering Portsmouth, Hampshire and West Sussex

Whether your dashboard lit up overnight or a garage has hit a wall with a tricky fault, we can help. Private customers, independent garages and used-car dealers all trust us to get to the bottom of it.

No guesswork. No unnecessary parts. Just the right diagnosis, carried out with the right equipment.

🔑 IMMOBILISER WARNING LIGHT ON? Don't panic.

That amber key symbol on your dashboard is your car saying it doesn't recognise the key signal. It's more common than you'd think. and it doesn't always mean an expensive fix.

Before you call anyone, try these first:

✅ 1. Check the key battery. A weak battery is the most common cause.
✅ 2. Try your spare key. If the spare works, the fault is with the key itself.
✅ 3. If both keys fail. you need a diagnostic scan to find out why.

A diagnostic scan reads the fault codes stored in your vehicle's immobiliser system. giving us a clear picture of what's actually wrong before any work begins.

At TCM Autolocks, we carry out dealer-level diagnostics using genuine manufacturer software. We come to you, at home or at work, across Portsmouth, Hampshire and West Sussex.

No guesswork. No unnecessary parts. Just accurate diagnosis and honest advice.

🔧 DEALER-LEVEL PROGRAMMING. WITHOUT THE DEALER PRICE TAG.

✅ Accurate fault finding, not guesswork
✅ SERMI-approved access for security-related work

We come to your home or workplace across Portsmouth, Hampshire, and West Sussex. and the job gets done properly, first time.

Whether you drive a BMW, Ford, Volkswagen, or most other makes. if it needs programming, we have the tools and the experience to handle it.

🔑 DID YOUR CAR COME WITH TWO KEYS?

This is one of the most important questions to ask — and one that could save you a serious amount of money down the line.

Here's the reality...

If you lose your only key to a modern vehicle, you're not just looking at a locksmith call-out. You could be facing:

✅ Full vehicle recovery costs
✅ Dealer-level programming charges
✅ Lengthy wait times with no vehicle to drive
✅ Bills running into hundreds — sometimes over £1,000

It's not a situation anyone wants to find themselves in. But the good news is — it's completely avoidable.

🚗 BUYING A NEW OR USED VEHICLE?

Before you drive away, make sure it comes with two keys. If the seller only has one, don't accept that as the norm — ask for a second to be cut and programmed before the sale, or factor the cost into your negotiations.

And if previous owners had additional keys for your vehicle, do everything you can to have those keys accounted for. It's not just about cost — it's about your vehicle's security too.

🔒 ALREADY ONLY HAVE ONE KEY?

Don't wait until you lose it to sort a spare. Get one cut and programmed now, while it's straightforward and affordable.

At TCM AutoLocks, we supply and programme spare keys for most makes and models across Hampshire and the surrounding areas — using genuine dealer-level equipment, without the dealer price tag.

That amber key light just came on. 🔑

It could be something simple like a low battery in your fob.

It could also be your immobiliser flagging a fault your car won't start without fixing.

Either way, guessing wastes time.

We carry manufacturer-level diagnostic equipment and come to you, at home or at work, across Portsmouth, Hampshire and West Sussex.

Message us today and we'll tell you exactly what's going on.
