A Retrospective What People Said About Truck Key 20 Years Ago
Keyless Entry Systems For Your Truck

In the 1980s, car burglaries using hot-wiring became more frequent. General Motors introduced "chip keys" or transponder keys to stop this.

The new car keys feature an electronic chip within the head of the key that transmits the car with a specific code. If the code is found to match, the engine will start.

Transponder Keys

Transponder keys are equipped with a microchip which transmits an electronic signal to the car's onboard computer when the key is put in the ignition. The computer on board of the car checks the code, and allows the engine to start if key is identical to the original. General Motors introduced this technology in the 1980s. It is now present in all cars and can deter theft by preventing unauthorized hot-wiring.

Unlike flat metal keys, a transponder key requires specialized equipment to duplicate. It is crucial to have your key fob programmable by a professional if you lose or break it. Locksmiths can program the key fob to work with the anti-theft system in your vehicle. Locksmiths can also assist you in recoding your key fob in case you discover it is not responding or locked.

To allow a transponder key to function properly, the key needs to be within seven feet of the vehicle's Engine Control Unit (ECU). When you insert your ignition key into the ECU sends an electronic signal to the chip in the key. This signal contains a unique code. The chip responds with its own unique code that is verified by the ECU. If the codes match the immobilizer system of the car disables the engine.

Certain manufacturers use an algorithm that rolls to make their transponder keys more secure. The code sent by the chip changes every few seconds. This stops any attempts by anyone else to read the chip and finding its password. It's important to maintain the battery on your key fob regardless of whether your vehicle utilizes rolling codes or crypto.

The added security the transponder car key offers is fantastic however, it's not inexpensive. The cost of a brand new car key that is transponder-compatible is about triple that of a standard flat key. But when you think about the cost it could help you with repairs and insurance costs by preventing theft of your vehicle, the extra expense may be well worth it. If you're considering buying a new key for your truck, remember to consider the pros and cons of each option to decide which one is best for your needs.

Key Fobs

Modern key fobs allow you to lock and unlock your truck without the use of a mechanical lock or key. The fob instead sends an electrical signal to a proximity sensor when it is within range. The reader then checks the signal and, if all is fine, it grants access. Most often fobs are used to gain access to buildings. However, they can also be used as car keys with remote starters. Some are programmed to open the trunk remotely. This is helpful when you have lots of luggage or groceries.

Fobs are tiny and compact devices equipped with the transmitter, microcontroller, and battery. The microcontroller is the brain of the operation and holds encryption keys that are resistant to hacking and the cloning. The transmitter takes the data from the microcontroller and sends it to the reader using electronic signals. The battery is the sole power source for the entire operation.

Proximity readers are able to be placed either inside or on the outside of a building to identify the signals from a key fob. The reader examines the signal against a database in order to determine whether it matches the credential that has been granted access. If the database can't detect it, the reader sends an electronic signal to deny access. Fobs can be paired with pin pads with numeric numbers (type in the pin number to unlock) and video intercoms or telephone call boxes for complete security systems that do not require physical contact.

Key fobs might be more expensive than traditional keys and locks, but they are also easier to use and are more durable. While a traditional key might eventually wear out due to constantly bouncing around in pockets and bags keys are made to withstand the rigors of daily use.

Fobs can be costly to replace when they're lost or damaged. Consumer Reports automotive expert Mel Yu says that replacing a BMW key fob can cost upwards of $400 because it has a unique digital encryption only available in the factory. You'll also need to have an additional mechanical backup key created which increases the overall cost of the replacement. Fobs for older cars are typically less expensive however.

Remotes

A key fob is equipped with transponder chips that transmit unique coded signals. The vehicle's receiver listens for the code and decodes it in order to determine whether or not it is appropriate to perform a task, such as locking or starting the engine. Each key fob has a unique identification code that is programmed into it during the manufacturing process and the car's computer confirms that the code it receives is one that matches its own stored code. This prevents thieves "capturing" the key fob's codes to unlock other vehicles in a mall parking lot, for instance.

The factory remote fob usually included in most trucks. However when you want to upgrade to remote starters, the new remote must have the same part number. This will ensure that it operates correctly. Auto Image clients in Brick and East Brunswick frequently inquire whether they can use their key fobs to control the remote start. But, the answer is not always clear.

If your key fob isn't responding when you hit the unlock button, make sure that all doors are shut. This will minimize the chance of RF interference from any electrical device might be in close proximity. You can also reset the key fob by following the directions in the user's manual. If this doesn't work, you will require the fob reprogrammed at the dealership or by a professional locksmith.

A key fob that has lost its connection to the receiver is another common problem. This could happen if the key fob is damaged or the battery has gone out of service. This typically indicates that the internal components have been damaged and the key fob needs to be changed. It's best to consult a local automotive locksmith or dealership for assistance, as it will likely require the use of specific equipment.

Keyless Entry

Keyless entry systems allow you to open your car without the need to insert a physical key. These systems use wireless communication protocols to authenticate the key fob to allow access to your vehicle. They can also control the functions of your vehicle and accessories and can adjust the exterior and interior of your vehicle in accordance to your preferences. These systems illustrate the automotive industry's shift towards advanced user experiences, increasing security and comfort.


The passive keyless entry system, also known as walk-away auto-lock, provides numerous life-changing features like locking your doors when you walk away from your car or turning on your lights before you enter. Certain systems can trigger up to ten electronic accessories in response to proximity to the vehicle. These technologies are a great choice for fleets, as they provide many advantages that increase productivity and efficiency while decreasing operating expenses.

truck key programmer employ rolling codes to stop unauthorized entry and hacking attempts. This keeps your vehicles secure from theft of valuable personnel and cargo. They also use encryption to secure transmission signals, further securing your vehicle from theft and ensuring the safety of your passengers. These security features are particularly beneficial for large fleets, as they can reduce the amount of time employees need to unlock their vehicles in a day and ensure that only authorized individuals are getting into trucks.

Installation: The keyless entry module is usually attached to the dashboard or under the steering column. It is connected to your vehicle's wiring. The most efficient method to install the system is to purchase a kit that includes a keyless entry module as well as wire harness and mounting hardware. After purchasing the necessary parts read the manual carefully and follow the instructions for installation. It's important to note that you'll need to take off the cover on your steering wheel to access the wires that you require. Once you've located the appropriate wires, strip a small portion of each and connect the proper connections. Then, wrap the unusable wires with black electrical tape to stop them from coming into contact with each other.
