Why Choosing the Cheapest Locksmith Can Cost You More: A Real Case from a 2018 Range Rover

When you lose your car key, it’s stressful enough. The last thing you need is poor workmanship, inflated pricing and further vehicle damage.

Recently, we were contacted by a very distressed customer who had lost the only key to their 2018 Range Rover. They had already been quoted £700 by another locksmith, significantly less than the £3,600 the main dealer had quoted, but unfortunately, the cheaper option ended up causing far more problems than it solved.

Here’s what happened.

The Problem: A Failed Attempt and Additional Damage

The original locksmith attended the vehicle but was unsuccessful in programming a new key. Worse still, during the attempt they:

• Damaged the vehicle’s KVM (Keyless Vehicle Module)
• Snapped a key inside the ignition
• Charged the customer £380 despite not resolving the issue

By the time the customer contacted Immotec, they were facing not only a lost key situation but also electronic damage that could have resulted in weeks of delays and potentially thousands more in repair costs if handled incorrectly.

Situations like this are more common than many drivers realise. If you’re unsure what your options are after losing your key, our guide on how to get a replacement car key explains the correct steps to take.

No Communication from the Vehicle

When we arrived, the vehicle had no communication with the OBD2 port, which is critical for programming new keys. This typically indicates a deeper issue within the vehicle’s control modules.

Rather than immediately recommending costly module replacement (as many would), we carried out a full diagnostic assessment.

We safely removed the damaged KVM module and brought it back to our workshop for detailed inspection and testing.

The Real Issue: Salvageable, Not Replaceable

Upon inspection, it became clear the KVM had been previously damaged during the earlier attempt. Fortunately, instead of replacing the entire module, which could have meant dealer-level costs and long waiting times, we were able to:

• Repair the KVM in-house
• Restore full communication
• Program new keys correctly
• Get the vehicle back on the road

The result? Another Range Rover back on the road without the need for expensive dealer intervention.

The Real Risk: Choosing Price Over Proven Capability

When you’ve lost your only key, cost understandably becomes a major factor. But modern vehicles — particularly models such as Range Rover — rely on complex immobiliser systems, encrypted modules and specialist diagnostics.

Key programming today is not just “cutting a key”.

In this case, the issue wasn’t avoiding the main dealer. The issue was choosing a provider based purely on price. The lower quote looked attractive, but:

• The correct diagnostic process wasn’t followed

• The KVM was damaged

• A key was snapped in the ignition

• The vehicle was left without communication

• The customer still had to pay

What started as a £700 solution quickly became a far more stressful and potentially expensive situation.

With modern vehicles, poor workmanship can:

• Corrupt control modules

• Disable immobiliser systems

• Lead to unnecessary part replacement

• Result in weeks of delays

The cheapest quote is not always the most cost-effective decision.

Why Experience Matters

Modern vehicles, especially models like Range Rover, rely on complex electronic systems. Attempting key programming without the correct tools, software, and technical knowledge can:

• Corrupt modules
• Cause communication failures
• Lead to immobiliser issues
• Create further expense

We regularly assist customers who have first tried a budget service, only to find the situation becomes more complicated.
