Truck Key Programming
Many customers visit your shop and hand you keys or fobs in disarray. Many customers will pay to repair the key or fob.
The majority of key fobs must be programmed by turning the ignition 'On then off within a time period. The vehicle will enter programming mode. This is usually indicated by the door lock's cycling or the audible chime.
Keys
One of the most valuable abilities that a mechanic can possess is being able to generate and program keys and fobs. It's a simple upsell for customers who are replacing keys that were stolen or lost, and is a great source of additional revenue for your shop.
lost truck key is a specialized field of automotive service that requires an understanding of the specific immobilizer system and its unique methods of getting an immobilizer pin code from the vehicle. Key programming also depends on the CAN/LIN bus system of the vehicle. They are designed to allow for communication between various Electronic Control Units in the vehicle or truck.
The ECU will backup the key data before programming the new one. The key data is stored in the Body Control Module. The manufacturer can use different names for this module. They include the General Electric Module (GEM), Central Electric Module (CEM) and Built-In Systems Interface (BSI), Front Electric Module (FEM), or Body Domain Controller (BDC).
Once the existing key data has been saved and the new key is ready to be programmed. Insert the new key in the ignition cylinder, and switch the key to the ON/RUN setting for approximately five minutes. Once that is done then turn the key OFF and then take it out. In a matter of seconds then, insert the working key that was previously programmed and turn it back to ON/RUN position.
This can cause an alarm light to flash. If this happens it is a sign that the new key was not properly programmed. Try again, changing the steps to turn on/off and then back to turn off/on. This should correct the issue and allow you to start the car using the new key.
Some vehicles require that you first enter the vehicle into an exclusive key programming mode. This is usually achieved by cycling the key to the on position, but without beginning the engine a specific number of times over a short time frame. Following this, you may require pressing a button on your key fob a few more times. If you have done it correctly, your car will enter programming mode. It will respond by changing the door locks, or displaying an audible tone.
Fobs
A key fob is fitted with a short-range transmitter and an RFID chip. The RFID chip transmits a unique coded signal to a reader through radio frequencies. The proximity reader then adapts to the signal and reads data from the RFID chip giving access to the user or removing the key if it's not the right one. Fob systems are designed to be compatible with specific reader devices, making them more secure than traditional locks.
Fob systems are usually integrated into larger security systems for buildings, giving administrators the ability to monitor users as they move around the facility and provide audit trails that detail their activity. They also reduce the need to change keys when tenants leave and enter or employees quit the company, which is a costly hassle. Fobs also provide better security than traditional keys, since they aren't easily duplicated or compromised.
Fobs are designed to guard your vehicle, however if you don't take the proper precautions, they could become vulnerable to hackers. They transmit a unique access/unlocking code each time and lock automatically after a set amount of time. Therefore, an attacker needs more than a key fob to successfully attack the system.
The majority of vehicles let you set up your own key fobs, without the need for any special equipment or a trip to the dealer. The procedure typically involves inserting the new fob into the ignition, then turning it off, and pressing buttons for a certain time. A chime will sound once the vehicle responds, typically by locking and unlocking the doors.
If your key fob isn't working properly, it may be a simple issue with the battery. Try replacing the battery, which can help restore functionality in a lot of cases. A common brand of battery used in key fobs is a coin available in most pharmacies and home improvement stores for a couple of dollars. If you're still unable to get your key fob to function, contact an expert. They are able to often identify the problem and recommend an alternative.
Remotes
Many trucks came from the factory equipped with keyless entry remotes that can lock, unlock and even start the vehicle. These remotes must be programmed into the vehicle to function correctly. You can try to program the remote yourself but it's likely to require a specialist, like a locksmith or dealership. They have the right equipment and tools to make sure that the new key can be correctly programmed.
The key fob is a tiny computer with a code that was programmed in during its manufacture. The car's receiver looks for this code in the RF signal transmitted by the remote when it is activated. This ensures that the car knows that this is the correct key to use, and only performs the action you request - such as locking or starting.

There are a few different ways to program the key fob in your car depending on the brand and model of the vehicle. Some of them can be programmed by the owner's manual, or online instructions. Some are easier to program, whereas others are more complicated. For instance, Nissan requires a specific sequence of steps to enter programming mode, which is easy to miss. Also, the key fob must be pointed at the receiver correctly in order to pair properly and program.
It is a risk to try and pair a second hand fob as the battery may be dead. Usually professional auto locksmiths or dealerships are able to program the key for your vehicle, and they can do this with an extra or even a replacement fob that you have purchased.
A professional can program a brand new key fob for you quickly and efficiently. If done correctly, the process could require only an onboard process, or a computer connected to the OBD2 ports. Some cars will require a more complex EEPROM procedure that only experts are able to carry out.
Keyless Entry
While rolling code technology can go a long way to provide security via wireless for keyless entry, it is possible for a purposeful replay attack to succeed [1]. This method involves recording the remote control signal, and then retransmitting the signal at an appropriate time. The receiver will interpret the new signal as authentic, allowing them to gain access to the vehicle or building.
Some systems are equipped with EEPROM reprogramming into the system to prevent this. This requires the use of special tools to extract and read data stored on a circuit board that is not accessible through the OBD2 port. This data can be used to program the transmitter by using the proper code. It is recommended to have a professional with extensive knowledge of the system in your vehicle perform this task.
The process is fairly straightforward. To program a keyfob with keyless access the driver's side door must be closed and then opened. Hold the LOCK button and the UNLOCK button simultaneously on the desired transmitter for a specified number of times within a set time period (for instance three times within five seconds). When the sequence is completed, the vehicle will enter programming mode. This can be exhibited by the door locks reversing (locking/unlocking) or the sound of a sound. It will only take some minutes to complete the procedure which allows you to leave Logan's roads and continue with your day.
