How much does a new Hyundai key fob cost?
It’s more likely that you will be allowed to utilize an aftermarket key fob if your automobile is at least ten years old, according to CR’s Ibbotson. Many of these less sophisticated fobs can be configured by the consumer, a local technician, or an automotive locksmith.
Ibbotson advises making sure to phone your neighborhood garage first to confirm that they can do the task, as key-fob programming equipment levels can vary from shop to shop. For instance, a Maryland-based repair shop called Murray’s Auto Clinics informed CR that they are unable to program key fobs for any vehicle with push-button start or keyless entry.
We took our vehicle to M.J. Sullivan Hyundai in New London, Connecticut, where we were charged $120 for programming (one hour of labor), which is what they would have charged us if we had purchased the key fob from them.
Hyundai sent us a laser-cut mechanical backup key for $72.47, bringing the total cost to $272.42 (the car waited at the shop for two days); if we had ordered the key fob through the store, the total would have been $428.92).
For some makes and models, you can purchase a cheap aftermarket fob and program it yourself if your home unexpectedly gains a third driver, such as a teenager.
We purchased a fob from BestKeys from Amazon for CR’s 2008 Chrysler Town & Country minivan. Although it lacks the Chrysler branding on the back, it resembles the two original fobs that came with the minivan when it was new. The uncut mechanical key and internal circuitry were both included in the $14.30 price. (However, we didn’t see the need to shell out the cash to have a locksmith cut that third key.)
Chrysler customers can program a third key fob themselves if they already have two functional ones, just like GM owners can. The owner’s manual contains clear and straightforward programming instructions.

One thing you must not permit is for the car to start on its own. You can find it difficult to start the car and get driving if the engine shuts off while the remote battery is low.

What occurs when the battery in your key fob runs low?
The transmitter’s range decreases as the fob battery gets weaker. This implies that for the key fob to operate, you must be close to the vehicle. When a smart key fob is in your pocket or handbag for automobiles with push-button starts, the car might not always detect it if the battery is low.
How long do the batteries in key fobs last?
Keyless entry is a fantastic feature, but you can only benefit from it if you keep the technology up to date.

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.

Okay, so you don’t have a spare battery and your key fob is dead. Not to worry. With a dead key fob, starting and unlocking your car is actually quite straightforward.

Here are a few tried-and-true methods that apply to a variety of automobiles.
If your key fob dies, can your car still start?
The majority of modern vehicles and light trucks start their engines with a Start button rather than an ignition key. Before the engine to start when you press the Start button, the Smart Key fob must send a coded signal to the button. If nothing happens, it could indicate any of the following:
Your key fob’s battery has to be replaced since it is either dead or functioning poorly when communicating with the keyless entry system.
The actual key fob is broken. This will necessitate getting a new key fob, either from the dealership or an aftermarket fob (which will have to be reprogrammed to your vehicle by a car dealer or certified locksmith).
The transmission gear selector is not in Park, you are not depressing the brake pedal, the brake pedal position switch is broken, or both. On automobiles with manual gearboxes, the engine won’t start until the clutch pedal has been fully depressed.
The Start button or keyless entry system is not working properly. The Start button may not be creating a signal when you press it down, or the keyless entry system may be unable to read the signal from the key fob due to an antenna or wiring issue. These issues will need to be diagnosed further, and you’ll probably need to have your automobile towed to a shop or a car dealer for repairs.
Your car’s battery is nearly dead or very low. Before your engine cranks and starts, this might need a jump start.
