MOT Test: Are Locks Included?

The MOT test is a crucial annual inspection designed to ensure your vehicle is roadworthy and meets safety and environmental standards. Many car owners diligently prepare for the common checks, like brakes, tyres, and lights. However, a question that sometimes arises is whether the more subtle components, such as the various locks in a vehicle, are actually covered by the MOT examination. Understanding the full scope of the MOT can help you avoid unexpected failures and keep your vehicle in tip-top condition. Let's delve into what the MOT test scrutinises and, specifically, how your car's locks fit into the picture.

What is the MOT Test?

The Ministry of Transport (MOT) test is a mandatory annual check for vehicles that are three years old or older in the UK. Its primary purpose is to ensure that vehicles are safe to drive and comply with environmental regulations. The test covers a wide range of components, from the most critical safety systems to emissions. The Vehicle and Operator Services Agency (VOSA), now part of the Driver and Vehicle Standards Agency (DVSA), sets the standards for the MOT test. Testers must be qualified and use specific equipment to conduct the examination. A vehicle will either pass the MOT test, receiving a certificate, or fail, requiring specific repairs before it can be legally driven on public roads.

Key Areas Inspected During an MOT

The MOT test is comprehensive, examining numerous aspects of your vehicle. These can be broadly categorised as follows:

• Body and Vehicle Structure: This includes checks for general condition, corrosion in specific areas, security of the chassis, and any sharp edges that could pose a danger.
• Fuel System: The fuel lines, pipes, and the integrity of the fuel tank are inspected for leaks or damage.
• Exhaust Emissions: The vehicle's emissions are tested against set limits to ensure it's not polluting excessively.
• Vehicle Identification Number (VIN): The VIN must be present, legible, and correctly displayed.
• Lights: All lights, including headlights, taillights, brake lights, indicators, and hazard lights, are checked for functionality, aim, and condition.
• Tyres and Wheels: Tyres must have adequate tread depth (minimum 1.6mm), be free from damage, and wheels must be securely fitted and in good condition.
• Brakes: A thorough inspection of the braking system, including the brake pedal, servo, pipes, hoses, and the efficiency of the braking system, is carried out.
• Steering and Suspension: Components like the steering wheel, steering column, power steering, suspension arms, springs, and shock absorbers are examined for wear and tear or damage.
• Windscreen: The condition of the windscreen is checked, particularly for chips or cracks in the driver's direct line of sight.
• Wipers and Washers: The ability of the wipers to clear the windscreen and the functionality of the washers are assessed.
• Horn: The horn must be present and working correctly.
• Seatbelts: All seatbelts, including pre-tensioners, must be present, correctly fitted, and in good working order.
• Airbags and Seatbelt Pretensioners: Warning lights for airbags and seatbelt pretensioners are checked.
• Engine: While the engine's internal mechanics aren't tested, the engine must not be excessively noisy or leaking fluids.

Are Locks Part of the MOT Test?

The direct answer to whether car locks are a specific item on the MOT checklist is no, not in the way you might initially think. The MOT test does not have a specific section dedicated to testing the functionality of your door locks, boot locks, or ignition barrel in terms of their security against theft. You won't fail your MOT because your central locking system is playing up, or because the key is a bit stiff to turn in the ignition.

However, this doesn't mean that issues related to locks are entirely irrelevant to the MOT. There are indirect ways in which lock-related problems can lead to an MOT failure:

1. Doors and Latches

The MOT test does require that all doors (including the tailgate or boot) open and close correctly from both the inside and the outside. This is checked under the 'Body and Vehicle Structure' category. If a lock mechanism is so faulty that a door cannot be opened or closed securely, or if a door cannot be opened from the inside, it will result in a fail. For example, if a door latch is broken, preventing the door from staying shut, this is a significant safety issue. Similarly, if the mechanism that allows the door to be opened from the inside is broken, this is also a failure, as it can prevent occupants from escaping in an emergency.

2. Boot/Tailgate Opening

Similar to the doors, the boot or tailgate must also be able to open and close securely. If the lock mechanism for the boot is so damaged that it cannot be properly secured, or if it cannot be opened from the inside (for example, if there's an internal release mechanism), this can lead to a fail. A boot that cannot be secured properly is a safety hazard, as items could fall out whilst driving.

3. Ignition Barrel

While the ability to start the car with the key isn't directly tested as a security feature, if the ignition barrel is so damaged or worn that it prevents the steering wheel from being unlocked, or if it's so loose it interferes with other controls, it could potentially cause a fail. However, this is less common, and the focus would be on the steering column's integrity and functionality rather than the lock itself.

4. Security and Alarms

The MOT test does not check the functionality of your car's alarm system or immobiliser. These are security features, not roadworthiness features in the context of the MOT. Therefore, if your alarm is faulty, it will not cause your vehicle to fail its MOT.

Common Lock-Related Issues Not Covered by MOT

It's important to distinguish between MOT failures and general vehicle maintenance. Many common issues with car locks will not affect your MOT pass certificate:

• Stiff or Sticky Locks: If your locks are a bit stiff but still function, they won't be a fail.
• Central Locking Faults: A malfunctioning central locking system, where only some doors lock or unlock automatically, is not an MOT failure.
• Key Fob Issues: Problems with your remote key fob, such as the battery dying or the fob not communicating with the car, are not relevant to the MOT.
• Minor Wear and Tear: Slight wear on the key or the lock cylinder that doesn't prevent operation is generally overlooked.

Preparing for Your MOT: What to Check

While the specifics of lock mechanisms aren't tested, ensuring your doors and boot open and close correctly is vital. Before your MOT, you should:

• Test All Doors: Open and close each door from the inside and the outside. Ensure they latch securely and don't require excessive force.
• Check the Boot/Tailgate: Make sure the boot opens and closes smoothly and latches properly.
• Inspect Door Seals: While not directly related to the lock, damaged door seals can sometimes impede the door closing properly, which could be an issue.
• Listen for Unusual Noises: If your locks are making grinding or unusual noises when operated, it might indicate a developing problem that could eventually affect the door's ability to latch.

Table: MOT Relevance of Lock Functions

Here's a quick summary of how different lock-related functions are viewed in the MOT test:

Frequently Asked Questions

Q1: Will my MOT fail if my central locking is broken?

A1: No, a broken central locking system will not cause your vehicle to fail its MOT, as long as each door can still be opened and closed manually and latches securely.

Q2: Is the ignition lock tested on the MOT?

A2: The ignition lock itself is not specifically tested. However, if its condition affects the steering column's ability to lock or unlock, or poses a safety risk, it could indirectly lead to a fail.

Q3: What if my car door won't open from the inside?

A3: If any door cannot be opened from the inside, this is a failure item on the MOT test for safety reasons.

Q4: Do I need to fix my car alarm before the MOT?

A4: No, the functionality of your car alarm system is not part of the MOT test and does not affect its pass or fail status.

Q5: Is a stiff door lock an MOT fail?

A5: A slightly stiff lock is unlikely to be a fail unless it prevents the door from being opened or closed securely, or from latching properly.

Conclusion

In summary, while the intricate security mechanisms of your car's locks are not directly scrutinised during an MOT test, the ability of doors and the boot/tailgate to open and close securely and safely is a critical part of the examination. Ensure all your doors and the boot latch correctly and can be operated from both inside and out. This attention to detail will not only help your vehicle pass its MOT but also contribute to overall vehicle safety. For any issues that do impact the MOT, seeking prompt repairs from a qualified mechanic is always recommended.
