Battery life is key, for both the transmitter and receiver, which must always be on, ready to receive a transmission. Some systems are designed to leave the receiver on for a short amount of time. For the ultimate in driver comfort and convenience, you can lock and unlock your car and start the engine — without even holding your key.
You simply need to have it on you, whether in your pocket or handbag. These type of systems, sometimes called Smart Keys or Passive Keyless Entry, are common in luxury cars. The doors unlock and open by when the driver pulls the handle. If they are, then carefully soldering them back in place may return your broken key fob to useful service.
They may be soldered back in place as well if you find that they have come loose unless a button is physically snapped off. In that case, you'll typically need to obtain a new remote. The rubberized buttons used by most car key remotes can fail in a number of ways. In that case, try removing the buttons, cleaning them, flexing them in and out, and then reassembling the remote.
If the buttons still don't work, you'll need to obtain a new remote. In order for a car key remote to work in a secure manner, it has to be effectively paired with the receiver unit in your car. This prevents anyone with the same make and model from walking up and using their fob to unlock your car. This is often accomplished by turning the key in the ignition several times with the doors shut.
Here's the basic procedure for a common key fob programming sequence:. Get in your vehicle, and close the door. Insert the keys in the ignition. Rather than start the vehicle, just turn the key to the run position and back to the locked position several times in a row.
The number of times will vary depending on your made and model of vehicle. If the engine cranks or starts, you've turned the key too far. Only turn it to the run position, not the start position. In the case that your vehicle uses is method of reprogramming, you will typically hear a chime after you have cycled the key several times. You can then press one of the lock or unlock buttons on the remote, after which you should hear the chime a second time.
If the procedure was successful, your key fob remote will work again. Different vehicles use different procedures.
Here's another one you can try if the first didn't work:. Get in your car and lock the door manually. Insert your key into the ignition and pull it back out six times within a maximum of just 10 seconds. If your vehicle uses this method, you will notice the exterior and interior lights flash. Insert your key into the ignition, and turn it to the accessory position.
Push one button on your remote. If the procedure is successful, the hazard lights will flash. Your key fob is now ready to use. There are other methods, and some require special equipment. In that case, you may have to contact your local dealer or an independent shop that has experience with your particular make and model of vehicle. If you have an aftermarket car security system that included remote-controlled door locks in addition to an alarm , then you'll need to check for any special reprogramming procedures associated with the system you purchased.
If nothing else works, there is always a chance that the receiver inside your car is broken or disconnected. The other option is to just buy a replacement remote, which you can obtain either new from your local dealer or used. If you buy a used one, you will have to reprogram your vehicle to recognize it before it will actually lock and unlock your doors.
Used car key remotes are typically cheaper than new ones, but costs associated with programming may outweigh the savings. Actively scan device characteristics for identification. Use precise geolocation data. Select personalised content. With a 2-way aftermarket solution, such as the Compustar PRO T12 , you can be sitting in your home or office and send a lock command to your car and you will receive a confirmation that your vehicle was actually locked.
Imagine getting into your work or office and trying to remember if you locked your car. Well, with a 2-way remote, you can press a button to verify that your vehicle was actually locked.
