Few things can be more frustrating than preparing to head out and discovering that the key to your car has suddenly stopped working. Perhaps the remote won’t unlock the doors, the key won’t turn in the ignition or your vehicle just won’t start. For a lot of drivers in Montreal, this issue tends to arise at the worst possible time — before work, while running errands or even after one-tenth of eight drinks in a parking lot.

Today, most vehicles use advanced key technology like transponder chips, remote key fobs, and even key-less entry systems. While such systems enhance security and convenience, they can also present new problems when something fails to operate correctly.

He’s not going to bum you out — all he knows is that the next time your car key inexplicably stops working, it doesn’t mean that some secret police in a black SUV is coming for you. In many cases the issue has an easy explanation and can be resolved quickly. In this guide, we’ll detail why car keys stop working and what Montreal drivers can do to resolve the issue — be it a quick battery change or consulting with a professional auto locksmith in Montreal.

Basics of How Modern Car Keys Work

Before discussing what can cause a key to fail, it helps to know how modern car keys work. Vehicular security systems mostly consist of a combo of mechanic and electronic setup on roads in Montreal.

Traditional Mechanical Keys

Older vehicles use basic metal keys that physically turn the lock and ignition cylinder. The keys don’t have electronic chips, which also means they can be replicated and repaired more easily.

While key entry works with fewer complications, non-electronic keys can also fail due to internal wear and tear over time.

Transponder Keys

The majority of keys are transponder types in cars made during the past two decades. Within the plastic head of the key itself is a small microchip that communicates with your car’s immobilizer system.

When you put in the key and turn it, the car verifies signal from the chip. So if that signal is correct, the engine fires up. Without the chip, the vehicle stays immobilized.

Remote Key Fobs

Remote key fobs let drivers lock and unlock their cars at the push of a button. Others add trunk release and panic alarm features.

These remotes function with small internal batteries that eventually deplete.

Contains Information on Smart Keys and Keyless Entry Systems

Most of Montreal’s newer vehicles have smart keys or start on push-button systems. A key does not need to be inserted for drivers to unlock the vehicle and start it.

These systems are handy, but because they rely heavily on electronics, they sometimes fail.

Dead Key Fob Battery

A dead key fob battery is among the most common reason that a key stops working.

Key fob batteries typically last two to four years. You may notice when the battery is low:

• The remote works only occasionally
  
• You have to be closer to the car for it to work
  
• Additional Features: The buttons lock and unlock completely
  

Cold weather in Montreal makes this problem even worse. Batteries deplete faster at low temperatures, causing many motors to suffer key fob failure during winter.

The good news is that a battery replacement takes about the same amount of time and isn’t expensive.

Damaged or Worn-Out Car Keys

Car keys are put through a lot of abuse every day. They get dropped, stuffed in pockets and exposed to moisture or dirt.

This can lead to damage over time in the form of:

• Bent or worn metal keys
  
• Cracked key fob cases
  
• Broken internal components
  

If the key is physically damaged, then it may not work properly, and in some cases, if it gets stuck in the ignition, turning will be impossible.

Many times, in such cases of lockout, drivers need to contact a professional locksmith in Montreal for car key replacement.

Transponder Chip Failure

The tiny microchip contained in a transponder key is essential for starting your car. If this chip gets damaged or fails to communicate with the car’s immobilizer system, the engine may fail to start.

Typically, the signs of chip failure are:

• The only thing that does happen is the key turns and the car won’t start
  
• A security or immobilizer warning light illuminates on the dashboard
  
• The vehicle starts intermittently
  

If you have a professional auto locksmith in Montreal examine this issue, they can reprogram or replace the key if necessary.

Key Programming Problems

And sometimes it’s not the key that’s broken, but rather the programming between key and vehicle that gets interrupted.

This can happen after:

• Replacing the vehicle battery
  
• Electrical system issues
  
• Resetting the software in the car’s computer
  

In such cases, the key must be reprogrammed using specialized equipment. Most mobile auto locksmiths in Montreal can do this on the spot.

Issues With the Car’s Locks or Ignition

The problem may not even be the key itself.

In some cases, the actual problem is with the vehicle’s locking system or ignition cylinder. For example:

• The ignition cylinder could be damaged or wearing out
  
• Debris could be stuck within the lock
  
• The lock mechanism might be stuck
  

These kinds of problems may make you feel like the key is failing to work, but in fact what is happening is a component failure at the mechanical level.

Extreme Weather Conditions

Montreal winters are brutal, and the cold has an impact not just on mechanical parts of a car but also on its electronics.

Winter conditions can cause:

• Frozen door locks
  
• Weak key fob batteries
  
• Sluggish electronic signals
  

Extreme low temperatures can cause damage to locks, and if your key fails to work suddenly in this kind of weather, it may just be the temperature playing a role.

How To Tell If Your Car Key Is About To Fail

Most car key issues don’t strike overnight. In fact, there are usually signs before the key fails completely.

Watch for these signs:

• The key fob works inconsistently
  
• It takes a few tries to start the car
  
• The lock or unlock buttons respond slowly
  
• The key sticks in the ignition
  
• Vehicle immobilizer light is often found on
  

“If you notice it is getting harder to press, don’t ignore that — get the key inspected.

What to Do if Your Car Key Is Not Working

If a car key suddenly stops working there are some steps to take before calling in a professional.

Replace the Key Fob Battery

If your remote won’t unlock the vehicle, check to see if it needs a battery replacement. Most key fobs contain small coin batteries that are cheap and simple to replace.

Try a Spare Key

Test a spare key, if you have one. If the spare functions properly, it’s likely that the original key — not your ride — is having problems.

Inspect the Key for any Physical Damage

Look for cracks in the key, bent metal or broken buttons. The key may be damaged physically and will not work properly.

Restart the Vehicle System

Occasionally electronic hiccups could result in momentary problems. Most issues can be addressed by turning off the car and starting it up again.
