Do Not Forget Peugeot Car Key Replacement: 10 Reasons That You No Longer Need It
New Key For Peugeot 207

The Peugeot 207 is a very popular car. It's a compact car with lots of character and style.

Over time, however they can develop problems. If not addressed immediately these issues could become quite grave.

Replacing keys for certain models of cars is a costly and stressful process, particularly when the car has been stolen.

Lost Keys

Peugeot is renowned for its top-quality cars. These cars have an extremely secure security feature that impedes the unauthorised use of the vehicle. The system utilizes the transponder, which is encrypted with a unique code. This enables the immobilizer to recognize the right key and start the engine. This keeps thieves away from using stolen Peugeot keys.

If you've lost your car keys, an auto locksmith professional can help. They will cut you a spare car key in your area. They can also program the key to work with Peugeot's immobilizers as well as lock barrels. This is a far less expensive option rather than going to a dealer.

The process for getting an additional Peugeot key is relatively simple for most models (except for the 107, 108, and Bipper). You will need to know the PIN code for your vehicle in order for obtaining an additional key. This can be a hassle especially if you are in a position with a limited amount of time to wait for the locksmith to arrive.

Transponder Fault

The immobilizer feature on your Peugeot 207 verifies that the key you used to start your vehicle is the one that it expects. This is done by transmitting a signal through an antenna that is connected to the microchip inside your key to the ignition. This is a security feature that protects your vehicle from being taken away.

Whenever the immobilizer control unit receives a signal from your key that isn't identical to the code it's expecting, it will illuminate the warning light on the console or flash quickly. G28 indicates that something is wrong and you may need to surrender your car to a Peugeot dealer with your registration card and identification document, in order to have the system reset and the keys reset.

If you bring your key to a garage that offers this service, they will scan it and determine whether the transponder has a problem. This service is completely free and they will tell you that your Peugeot is not starting because of a problem with the system.

If you've swapped the original Peugeot key case for another (and therefore lost the transponder chip), or you have damaged your key by getting it wet, it's nothing to be concerned about. The most common problems with the immobilizer system arise caused by a weak battery in your key, a damaged antenna, or a malfunctioning electronic within the module and the engine computer.

Key Blade Wobble

Peugeot decided to do something different in early 2000. In the early 2000's, the company introduced a flip-key design instead of the traditional transponder chip that was encased in carbon. The new design has many major issues and one of the main ones is key blade wobble. This problem occurs when the key blade, which is basically the mouthpiece that is inserted into the lock first, wears. This causes the silver button inside the key to stop flipping out the mechanism, and the key ceases to feed into the lock properly.

This is easily fixed with a new blade cut to code. It is important that the blade is copied from your old worn-out key, and not a generic replacement since it won't give you a genuine shape and will wear exactly in the same way that the original key did. Your local Car Key Man auto locksmith can make a new blade and resolve this issue.

Key Blade Damage

Quite often, the blade of the key gets damaged, or more accurately the 'mouth' of the key, wears out. This can cause the key to become stuck in the lock if it isn't removed in a timely manner. This then leads to the dreaded 'Immobiliser Fault' on your dashboard. There are a myriad of fairy tales on how to fix the problem, but in fact you need a new blade.

This is a relatively cheap task that can be performed by your local Car Key Man Auto Locksmith. They'll simply need to cut a fresh blade and put it on the Peugeot 207 key.

The circuit board that creates the signal for the transponder chip will start to show tiny hairline cracks after about five years. These cracks aren't affecting the chip, but they can cause other problems with your Peugeot key.


The flip mechanism, which holds the blade in position, is not very reliable. This is particularly relevant to the Peugeot Partner, Peugeot 107 and Peugeot 407 ranges. This is because the key's "flip mechanism" has changed from the earlier model that was carbon-encased. This change has caused four major issues that may stop your Peugeot key from functioning.
