Weak Signals
If your key fob isn't able to respond to the buttons on the remote it could be a sign that the signaling is not functioning correctly. Your car and key fob are dependent on radio signals to communicate, therefore weak or inconsistent signals could result in poor range and performance.
One of the first things you should examine is whether your fob's battery is low because this could significantly affect the sensitivity of the signal. It's also worth resetting the settings of your fob and help restore the same response from the car. The process will vary from vehicle to vehicle. The owner's manual or a call to your manufacturer's support line is your best source of information.
Other factors can cause weak fob signals, such as interference from other devices operating at the same frequency as your key fob. Power lines and other key fobs wireless communication devices, and even cell networks can interfere with the RF (radio frequency) signals that your key fob uses to connect to the receiver inside your vehicle.
Additionally physical damage to your key fob can affect the transmission of RF signals, which could result in a decrease in performance and range. A blown fuse, a damaged or cracked button or a bent case can all interfere with the transmission of signals and cause the remote to fail to respond.
There are some simple steps you can follow to try and solve the issue of weak fob signals, for example, resetting the fob's settings, or replacing the battery. If your fob has become old and worn, it could be time to replace it.
Also, don't forget if you have a spare key fob that is part of your vehicle, it could be used instead of the primary remote if it begins to fail. You should test this option first to see if you can resolve the issue before purchasing another remote. In this instance it may be an appropriate time to consult an auto-locksmith professional. They will be able to identify the issue and recommend the best course of actions.

Lost Fob
Even with the best care, car key fobs can fail at times. It's costly to replace yours if you lose it and especially if you do not have an extra. "You might end up paying $50 or more for a new replacement from a dealer and get it programmed, and a new mechanical backup, which could cost you at least another $100," says Mel Yu who is an automotive analyst at Consumer Reports.

A locksmith is in a position to assist you in finding the lost fob or have it replaced. A locksmith will probably know why your fob stopped functioning in the first in the first place. And if your vehicle is a model older than the one you own and has no built-in smart technology, you can save some cash by locating the key number plate on your current mechanical backup key (it's typically hidden behind a decorative keychain) and recording it in a secure place, such as your wallet or on your phone. This can make it easier for the locksmith to reprogram the new key fob for your car if you ever need to do it.
If your key fob is an older smart key, it'll have to be deprogrammed by a locksmith or a car dealer. This could cost more than simply replacing it.

And that means locksmiths need an exclusive programing tool that only the vehicle manufacturer is equipped with, which adds to the overall expense.
In most instances, you'll have to pay for the entire service at once, which includes any charges to reprogram a new key fob. This can range from $20 in some stores to more than $200 at car dealerships, depending on the model of vehicle.
