If your Jeep compass key fob has difficulty transmitting signals, this may be caused by its battery. Over time, key fobs tend to lose some of their operating range.
If this occurs, the battery in your Jeep compass key fob should be changed immediately. Replacing it is simple and only requires minimal tools for installation.
How to Change the Battery
Your Jeep Compass key fob might no longer work due to any number of reasons, including dead batteries or loose or disconnected wires within its construction.
Finally, dropping it in water could damage its internal components resulting in irreparable internal damage to its components.
Replacement is often the solution to these issues and should only take a few minutes using standard tools such as a flathead screwdriver.
Beginning by positioning the screwdriver tip along the seam of your key fob, gently pry open (but without twisting its plastic). Your battery should be inside. Make a note of its polarity for use as an easy guide when installing new batteries – once you have them all installed and assembled again, test to ensure proper functioning!
Tools You Need
Jeep key fobs function as short-range radio transmitters that send coded signals directly to the vehicle. If this signal becomes lost, you may no longer be able to start your car with just the push of a button, due to various causes such as bad batteries or radio interference from devices such as radar detectors or anti-theft alarms that transmit on similar frequencies as your key fob.
If this occurs to you, replacing the key fob battery is often the solution. The process is straightforward and can easily be accomplished at home with standard tools; all that’s necessary for replacement is a flathead screwdriver and new CR2032 battery. Be mindful to record its polarity before removing old one; this will help orientate new one properly once installed in key fob. Once all batteries have been switched over carefully reassemble key fob.
Dismantling the Fob
Jeep key fobs send coded signals over short range to their receiver. As their batteries begin to discharge, these codes become unreadable by their receiver. When this occurs, these signal cannot reach it’s destination as intended and cause havoc within your vehicle.
Thus, you may experience issues like multiple button presses required to unlock door locks or an abrupt loss of key fob coverage; radio signals from radar detectors or anti-theft alarms might even interfere with signal transmissions and be blocking your signals altogether.
To dismantle a fob, insert the tip of your screwdriver into a seam near the black plastic key ring loop on one side, using its blade to carefully pry apart both halves without harming any electronic components within. After prying apart both halves without damaging electronic components inside, remove and store away the black switch that releases backup metal ignition key; install new battery properly into its holder by aligning its “+” positive side downward while making sure its “-” negative side faces towards you when installing battery holder; do this to ensure proper installation into its holder with its “+” positive side down and its “-” negative side facing away from you before installing battery into its holder and making sure its “+” positive side facing downward while facing away from you to ensure proper positioning in its holder!
Installing the New Battery
Whenever your key fob stops working properly or shows that there’s no power in it, replacing its battery should be the top priority. This process is quick and can be completed using standard tools and a new CR2032 battery in minutes.
An effective tip when replacing batteries in key fobs is taking note of their positions in advance so you can ensure the new one fits without issue. This way, you can ensure a flawless experience when inserting new ones.
As you install your new battery, keep this tip in mind: for most key fob batteries, the positive side should face downward and negative up. This can make life much simpler when trying to identify where each side belongs.
