Truck Key Programming
Many customers will come to your shop with keys or fobs that are damaged. They usually pay for you to make the key or fob work again.
Most key fobs need to be programmed by turning the ignition 'On and off within a certain time period. The vehicle will enter the programming mode, usually signalled by the door locking mechanism chiming or a chime that sounds.
Keys
One of the most valuable skills that a mechanic has is the ability to generate and program keys and fobs. It's an easy way to sell customers who need to replace lost or stolen keys and is a fantastic source of extra revenue for your shop.
Key programming is a highly specialized area of automotive service that requires an understanding of the vehicle's immobilizer system and its unique methods of acquiring a pin code from the vehicle. Key programming also requires the CAN/LIN bus system of the vehicle. These are designed to facilitate communication between various Electronic Control Units in the car or truck.
The ECU will backup the key data before programming a new one. This information is stored in the Body Control Module. The manufacturer may utilize different names for this module. These include the General Electric Module (GEM) Central Electric Module (CEM), Built-In Systems Interface (BSI), Front Electric Module (FEM), or Body Domain Controller (BDC).
The new key can then be programmed after the current key data is backed up. To do this, simply insert the new key into the ignition cylinder and then turn it to the ON/RUN setting for approximately five seconds. After that you can turn the key OFF and then remove it. Insert the key that you previously programmed and turn it on the ON/RUN.
This will usually cause an alarm light to flash. If this happens it is a sign that the new key was not programmed correctly. Try again, reversing the steps to turn off/on and then back to on/off. This should resolve the issue and allow you to use the new key to start the car.
Some vehicles require that you first switch the vehicle into a special key programming mode. This is typically accomplished by resetting the key to the on position without starting the engine a certain number of times over an extremely short time. Following this, you may need to press a button on your key fob several more times. If you have completed the procedure correctly, your vehicle will enter programming mode. It will then respond by cycling the door locks and/or displaying an audible tone.
Fobs
A key fob is a short-range radio transmitter and an RFID chip that uses a set of radio frequencies to send a unique coded signal to the reader device. The proximity reader adjusts to the radio signal and reads the information from the RFID chips and allows access to the user, or deactivating a key if the key isn't the correct one. Fob systems work with specific readers that make them more secure.
Fob systems can be incorporated into larger building security systems that allow administrators to monitor the movements of their users and provide audit trails detailing their activities. They can also save you money by not having to change keys each time tenants move in and out of the building, or employees leave. Fobs are also more secure than traditional keys, as they are not easily duplicated or hacked.
Although fobs are designed to be secure, they can be vulnerable to hacking if appropriate precautions aren't taken. They transmit a unique access/unlocking code each time and lock automatically after a set amount of time. Therefore, an attacker needs more than the key fob to be able to attack the system.
Most vehicles allow you to program your own fobs, without the need for special equipment or a trip to a dealership. The procedure typically involves inserting the new fob into the ignition by turning it on and pressing buttons within a specific time frame. A chime will sound once the vehicle responds. Usually, this happens by locking and unlocking the doors.
If your key fob does not function properly it could be a simple problem with the battery. In many cases replacing the battery is the best option to restore the functionality. A common brand of battery used in key fobs is a coin cell that can be found in many pharmacies and home improvement stores for just a few dollars. If you're still having trouble getting your key fob to function, contact an expert. They will be able to pinpoint the issue, and often give you a new key fob.
Remotes
Many trucks came from the factory equipped with keyless entry remotes that can lock, unlock, and start the vehicle. The remotes have to be programmed with the car in order to work properly. You can try to program the remote on your own, but it will probably require the assistance of a professional like a locksmith, or a dealer. They have the right equipment and tools to make sure that the new key is programmed correctly.
The key fob is a tiny computer with a code that was programmed during manufacture. The car's receiver is looking for this code in the RF signal that is transmitted by the remote when it is activated. The car will only perform the action you request only if it's certain that this is the right key.
There are several ways to program the key fob of your vehicle, based on the make and model of the vehicle. Some of them can be self-programmed using the owner's manual or online instructions. Some, however, are more complicated. Nissan, for example, requires a certain sequence of steps in order to enter programming mode. This is often overlooked. The key fob must be properly aimed at the receiver for it to pair correctly and program.
It's risky to pair a second hand fob, as the battery might be dead. Typically, professional auto locksmiths or dealerships will be capable of programming the key to your vehicle and do this using the spare or replacement fob that you've purchased.
A professional can program your new key fob quickly and efficiently. The process may only involve an onboard procedure or a programmer that is connected to the OBD2 port and is fairly secure if it is done correctly. Some cars, however, will need an even more complicated EEPROM procedure that only experts know how to do.
Keyless Entry
Although rolling code technology has gone quite a ways to provide security via wireless for keyless entry, it is possible for a purposeful replay attack to succeed [11. This technique involves recording the remote control signal and then retransmitting at a convenient moment. The receiver will interpret the new signal as authentic, allowing them to gain access to the vehicle or the building.
To prevent this from happening, certain systems have EEPROM reprogramming built into the system. This requires special tools to extract and read information stored on a circuit board that is not accessible through the OBD2 port. With this information, it's possible to program the transmitter using the proper code. This can be accomplished by a professional with a thorough knowledge of the vehicle's system.
The process is pretty straightforward. To program a keyfob to allow 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 certain number of times within a set time period (for example, three times in five seconds). After this sequence has been completed the vehicle is in programming mode, indicated by door locks cycling (locking and unlocking) or an audible chime. truck key copy should only take a few seconds, allowing for you to go about your day through Logan's streets.
