Majority of the cars manufactured in the last fifteen years have had some options of key less entry, and it’s becoming more popular nowadays. But how do these remote keys work?
The remote key has a radio transmitter with a short range. This works between the radius of twenty metres approximately. The system is same as the one used to open garage doors or electronic locks. The transmitter sends a specific signal with a code. If the code matches with the receiver, it activates the mechanism, resulting in opening of the garage door or disengaging the electronic lock.
Active remotes have a button on them. When you press the button, a transmission is sent with a specific code communicating with the receiver. The transmission spreads out in all directions. This is the reason your car unlocks whenever you point the key. The transmission has a specific code so that it doesn’t match with other cars. However, if the keys malfunction you should not try to fix it on your own and instead hire a professional mobile automotive locksmith.
Passive keys are also known as smart keys. These are the more recent additions in the industry of keyless entry. They transmit commands without the need to press any button. The keys have an array of LF (low frequency) antennas (generally four to six antennas). These antennas produce a magnetic field round the car. The key fob normally stays in sleep mode which keeps an extremely low powered LF detector. Whenever the LF field around the car gets detected, the key fob switches on automatically and begins transmitting the code.
Security & Encryption
Security is an extremely crucial factor for most keyless entries. There are a number of key fobs out in the market, and it’s vital to check and make sure that they don’t respond with others. Additionally, the security must be of a strong category so that no one can easily duplicate the code, and gain access into the car.
This is why, the complicated security is handled with a specialised form of heavy-duty encryption. Each car manufacturer has their own method of encrypting their keys, so that they don’t match with others. The latest encryption key comes with a 128-bit encryption. This means the code has 128 characters, or about 339 decillion combinations. The encryption is implied on a changing or rolling basis. The transmitter and the receiver are synchronised with a program to generate a new key code every time.
Thus simplified, that keyless entry systems are the best method to keep a car safe and nullify the hassles of losing car keys.
Common signs of a sub-standard or failed ignition lock include total stop-over of your car, the key getting stuck in the ignition or not even going inside the ignition hole.
Before you know the symptoms you must be familiar with the ignition lock. The ignition lock cylinder is a cylindrical tumbler that powers the engine and starts the vehicle. While most of the new vehicles now come with keyless power and push button starting systems, traditional ignition lock cylinder can be still found in many cars and SUVs.
Most ignition lock cylinders have four different responsibilities.
- Unlocking the steering wheel
- Supplying power to the vehicle’s accessories
- Starting the vehicle’s computer and fuel system
- Cranking and activating the engine
This is why, your car stays in complete idle position with a faulty ignition lock. Usually the lock produces a few symptoms which you need to know. Learning about the issues will educate you about the car’s ignition systems and why the car is not moving. Then accordingly you can call in a professional mobile automotive locksmith and have the issue resolved suitably.
1. Powering the vehicle
One of the first symptoms you will notice in a failed ignition lock cylinder is the issue of powering the vehicle. When you repeatedly turn on the ignition lock, the engine gets started but begins to wear out soon after. A faulty ignition key means it is having issue with certain positions of the key. The embossed surfaces may not work correctly, or may require jostling before they start working. The problem will gradually worsen until the unit fails completely.
2. Car not starting
Another symptom of a possible ignition lock issue is a no-start condition. The cylinder of an ignition lock is connected to the electronic ignition switch in your car. Its job is to power on and start the vehicle. If the ignition lock cylinder breaks or wear out, it may prevent the vehicle from getting started.
3. Issue with inserting and extracting the key
Issue with inserting and extracting the key is another symptom of a potential ignition lock problem. Do not repeatedly try to insert, turn or extract the key as it may cause both the cylinder and the key to wear out and cause issues with the operation.
In general, getting familiar with the ignition lock system can avert future problems and moreover, you can tell the professionals about the exact issue, thereby saving yourself a lot of time.
