A car’s battery can a key fob drain it?
We frequently receive inquiries like these at the shop. Yes, it is the correct response. Your key fob can eventually deplete your battery if you keep it in your car when it is not in use. Even when not in use, the key fob continuously transmits a signal to the vehicle, which consumes a tiny amount of electricity. So, if you keep your key fob in your car for a long time, the battery will ultimately die. If you find yourself in this predicament, you might try using a jumper wire or a portable battery pack to jump start your automobile.
Additionally, it may not be a good idea to leave your key fob in your car overnight or even just hanging nearby. The key fob may speak with your automobile if it is too close, which could drain the battery.

But what occurs if the fob breaks down? The key fobs for your car require maintenance just like the vehicle itself does.
When anything breaks down, Gary Freeman, owner of C & G Auto in Myrtle Beach, advised against replacing it right away.
“A replacement fob can be pricey; they can cost several hundred dollars, and once you have a replacement fob, they need to be programmed,” said Freeman.
He advises checking the battery as your first action. If you have to press the lock or unlock button on the remote numerous times before it locks or unlocks, it could be a sign that the battery is starting to lose power, according to Freeman.
According to his calculations, the keyless entry remote can be safely stored or hung up anywhere beyond the six to ten feet from which the automobile computer system can read the fob.
According to Freeman, the battery life for the majority of automotive key fobs is three to four years with regular use. Additionally, he claims that the battery life of your fob may be impacted by where you keep it. Freeman advises against hanging the fob near the car or leaving it in the car overnight.
“It (the key fob) does send a signal continuously, so it drains the battery in the key fob and its causing an excessive drainage on the battery of the automobile,” noted Freeman. “A computer is identifying that signal saying I’m ready to start.”
According to Freeman, if the key fob malfunctions, the automobile frequently won’t start because the computer system won’t acknowledge that the key fob is present in the vehicle.
“In most situations, the owners’ manual will clear that up for you, or practically any auto repair facility can replace that battery,” Freeman continued.
Why won’t my key fob work with my car?
Key fob battery failure The most frequent cause of a keyless entry system failing to send signals is a faulty battery in the key fob. Use the extra key fob to unlock the car and turn on the ignition if one is available. Use the key that is included in the spare fob if it is not available to unlock the door.
Can a key fob be programmed without visiting the dealership?
According to John Ibbotson, CR’s head technician, “If you have a car that was constructed within the previous five years, a new-car dealer will typically be your best chance when you need a replacement key fob.” This is because expensive programming equipment is needed.
We discovered from Audi and Subaru dealers that some key fobs won’t function with aftermarket key fobs, despite the temptation to go for a less expensive one online.
A service advisor at Hoffman Audi in East Hartford, Connecticut remarked, “If you want a new key fob for your Audi, it has to come from us.” The key fob has a built-in security chip that cannot be modified to work with another Audi. A new aftermarket Audi key fob cannot be purchased online because of the requirement for this chip. He claimed that “the fob has evolved into a crucial component of the security of the car.” We were informed that the typical cost of replacing an Audi key fob, including programming, is $500.
This applies to all European vehicles, not just Audi. Because the manufacturer can only program the digital key encryption in a small number of exclusive stores in North America, they nearly always require the customer to see a dealer, said Yu of CR.
Other merchants we contacted, such a Lexus dealership and a Chrysler/Jeep/Dodge dealership, stated they don’t mind attempting to program aftermarket fobs if the buyer requests it as long as the customer is aware of the dangers.
We were advised by a service advisor at a Lexus dealer that they were reluctant to work with aftermarket key fobs. If we try to program it and it doesn’t function, we still have to bill them for our efforts, we can’t warranty parts or labor.
Fortunately, even if you have to visit a dealer, the procedure is quick. Key-fob programming, according to the majority of the dealers we spoke with, usually only requires 15 to 30 minutes, and the entire process, including creating the mechanical replacement key, rarely lasts longer than an hour.
Even if they handle everything for you, going to the dealer doesn’t have to be expensive. Even with European brands, this held true. A replacement fob with a laser-cut key and programming for CR’s 2015 VW Jetta would cost roughly $225, according to a local Volkswagen dealer with whom we spoke.
Customers can save money on programming with some companies, like Chevrolet. For instance, a Chevrolet official informed us that the key-fob programming does not need to be done at the dealership and that General Motors key fobs are on the more affordable side ($147.98 for a 2019 Chevrolet Malibu with keyless entry, push-button start, and remote start).
The car must be present, he added. “The programming technique is explained in the vehicle owner’s manual.
Be advised that most customer-programmable key fobs, regardless of brand, require two active, functional keys in order to program a third new key without visiting the dealer, according to Yu.
How can I tell if my key fob is defective?
The majority of modern fob keys can often communicate with a car up to 50 feet away. Many owners of cars, trucks, and SUVs use this feature to lock or unlock their vehicles as they move away from them or as they approach them. However, the fob transmitter’s range and signal power will decrease as the battery ages. It may be necessary to change the batteries if you find that your key remote is not working as quickly as it should to unlock, lock, or start the engine for vehicles with automatic start buttons.
Will a dead key fob prevent a car from starting?

This function depends on the battery in your car’s key fob; if it runs out, you might not be able to start your car without a jumpstart. Your ability to start your car may be affected if the battery in your Honda keyless remote is low.
