Old Peugeot Citroen 0523 Folding Remote Control Key 433MHz 46 Chip Black

This folding remote control key is a replacement part for older Peugeot and Citroen vehicles that use the 0523 key groove pattern. It operates on a 433MHz frequency and contains a 46 chip, matching the original specifications described in the source information. The key is black and comes with a circuit board battery already installed. It is an original consumable item, so it is not a universal key. Before buying, you must check that your existing key has the same frequency, chip, circuit board, and the 0523 marking in the key groove. The key does not arrive pre-programmed and cannot be matched by the owner. A professional locksmith, auto repair shop, or 4S shop must carry out the matching procedure. This product is intended for drivers who need a replacement folding key for an older Peugeot or Citroen and who can arrange professional programming.

Features and Construction

The key is built as a folding remote control unit with a black finish. It includes a circuit board and a fitted battery, ready for the matching process. The 433MHz frequency and 46 chip are stated specifications that must match your original vehicle setup.

Material and Build

The folding key shell is made of plastic, as is typical for this type of remote key. Inside, the circuit board carries the 46 chip and the battery is already installed, according to the source text. The key groove is marked with 0523 characters, which must correspond to the original car's key groove. No other materials are specified in the source information. The build is intended for use as an original consumable replacement part.

Size and Practical Fit

No measurements are provided in the source text, so no dimensions can be given. The practical fit depends entirely on the 0523 key groove marking, the 433MHz frequency, and the 46 chip. These three details must match your existing key for the product to be suitable. Because no size data is available, you should rely on the model and groove information rather than physical dimensions. If your original key does not have the 0523 marking, this key will not fit.

Uses and Placement

This key is used as a replacement for an old Peugeot or Citroen folding remote key. It is not a standalone product that works without professional matching. The main use case is restoring a functional key for a vehicle that already uses the matching 0523, 433MHz, 46 chip setup.

Event or Professional Use

Professional matching is required. A locksmith, auto repair shop, or 4S shop must program the key to the vehicle. The owner cannot complete this step. The circuit board battery is already installed, which supports the matching process, but it does not remove the need for specialist equipment. This key is therefore suited to situations where you can take the vehicle and the key to a qualified professional.

Everyday Home Use

Once matched, the key is used as a normal folding remote control for everyday driving. The folding design allows the key blade to be tucked away when not in use. The black finish is the only colour option stated in the source. No further everyday features are described, so no additional claims can be made about convenience or performance.

Benefits and Buying Value

The main buying value is that this key provides a replacement option for older Peugeot and Citroen models with the specific 0523, 433MHz, 46 chip configuration. It comes with the circuit board battery installed, which is one less item to source separately.

Reuse and Low Maintenance

The source text does not provide maintenance instructions beyond the note that the circuit board battery can be used for this product. No lifespan or service interval is given. Because it is an original consumable, the key is intended to replace a worn or broken unit rather than to be repaired. Any maintenance beyond battery replacement should be handled by the professional who matches the key.

Why Choose This Product

Choose this key only if your original key matches all stated details: 0523 key groove, 433MHz frequency, and 46 chip. It is not a universal fit and the owner cannot program it. The product is suitable for drivers who understand that professional matching is required. If your key differs in any of these specifications, this product will not work for your vehicle. No price, savings, or competitor comparisons are provided in the source, so none are claimed here.
