Are you experiencing issues with your Ford Transit key fob? Is it becoming less responsive, or perhaps not working at all? A common culprit for these problems is a dead or dying key fob battery. While it might seem like a simple fix, changing the battery in a Ford Transit key fob can be a bit more complex than in other vehicles. This guide will walk you through what you need to know about Ford Transit key fob batteries and how to address battery issues.
Understanding Your Ford Transit Key Fob Battery
Unlike some key fobs that use easily replaceable coin cell batteries, many Ford Transit key fobs, particularly in older models, come with rechargeable batteries that are soldered directly onto the circuit board. This design means that the battery is not intended to be routinely replaced by the owner.
These rechargeable batteries are designed to replenish their charge while the key is in the ignition. This system is convenient as it theoretically eliminates the need for regular battery changes. However, like all rechargeable batteries, these can degrade over time and eventually fail to hold a charge effectively.
Is Your Ford Transit Key Fob Battery Rechargeable or Replaceable?
Determining the type of battery in your Ford Transit key fob is the first step. If your key fob is older, or if you’ve had it for many years without battery changes, it’s likely equipped with a rechargeable battery. Signs that your key fob has a rechargeable battery include:
- No Easy Access Panel: The key fob casing may not have an obvious, easily accessible compartment for battery replacement, secured by a small screw or clip.
- Recharging Expectation: You may have been told or read that the key fob battery recharges while driving.
If your Ford Transit key fob is a newer model, it might use a standard, replaceable coin cell battery. These fobs will usually have a small access panel, often on the back, that can be opened to replace the battery.
Options When Your Ford Transit Key Fob Battery Dies
When your Ford Transit key fob battery starts to fail, you have a few options:
1. Attempt to Recharge (If Applicable)
If you suspect you have a rechargeable key fob battery, the first step is to try and recharge it. Simply using your Ford Transit as you normally would for a few days, ensuring you drive it and use the key in the ignition, might be enough to revive a battery that has just become slightly depleted.
However, if the battery is old or significantly degraded, recharging may not be effective.
2. Professional Key Fob Repair or Replacement
Given the complexity of soldered batteries in some Ford Transit key fobs, seeking professional help is often the most reliable and safest option.
- Ford Dealership: Your local Ford dealership can diagnose the issue and offer key fob replacement or, in some cases, repair services. Be aware that dealership replacements can be more expensive, potentially costing around £100 or more, as mentioned in user experiences.
- Auto Locksmith or Key Fob Repair Specialist: Specialized auto locksmiths or key fob repair services are often a more cost-effective alternative to dealerships. They may have expertise in soldering and replacing the rechargeable battery itself or offer a more affordable key fob replacement solution. These specialists are more likely to attempt battery replacement at a component level.
3. DIY Battery Replacement (Advanced and Risky)
If you possess advanced DIY skills, particularly in soldering and electronics repair, you could attempt to replace the soldered battery yourself. However, this is not recommended for most users due to the risks involved:
- Soldering Skill Required: Removing and replacing a soldered battery requires precise soldering skills and equipment. Incorrect soldering can easily damage the circuit board, rendering the key fob useless.
- Battery Availability: Finding the correct replacement rechargeable battery with solder tabs may not be straightforward.
- Risk of Damage: Working on delicate electronics always carries a risk of causing further damage, potentially leading to the need for a complete key fob replacement, costing even more in the long run.
If you choose to proceed with DIY replacement, proceed with extreme caution and only if you are confident in your abilities. Online guides and videos, like the one mentioned in the original forum post (http://www.sprintmanchester.co.uk/help-page/how-to-repair-a-ford-transit-key-fob/), can offer some insight, but professional expertise is always advised.
Conclusion
Changing the battery in a Ford Transit key fob can range from straightforward to complex, depending on the type of key fob you have. While some newer models might allow for simple coin cell battery replacement, older models often feature soldered, rechargeable batteries that are not designed for user replacement.
For most Ford Transit owners experiencing key fob battery issues, seeking professional help from a Ford dealership or a specialized auto locksmith is the most practical and reliable solution. Attempting DIY repair on soldered batteries should only be considered by those with advanced electronics skills and a clear understanding of the risks involved. Prioritizing professional service ensures the job is done correctly, protecting your key fob and avoiding potential further complications.
