A a glance: sorting out your Jaecoo key
- If your Jaecoo smart key has no conventional exposed keyring eyelet, plan how you will carry it before adding it to a bunch of house keys.
- A correctly fitting protective cover with its own attachment loop is usually the neatest way to add a split ring, clasp or lanyard without altering the original key.
- Match a cover to the exact shape and button layout of your key. The model name alone is not always enough.
- Do not drill, glue or force anything through the original fob, its emergency-key release or the gap between the casing sections.
- Keep the attached keyring reasonably light so it does not strain the cover or make the fob unnecessarily bulky.
- For a keyless vehicle, keep both the everyday key and spare away from doors and windows at home. Signal-blocking storage can add protection against relay theft, but it is only one layer of vehicle security.
A new Jaecoo owner can leave the dealership with two smart keys and immediately discover a surprisingly ordinary problem: the smooth key-fob design may not provide the sort of obvious metal eyelet found on a traditional car key.
That is not a problem if you are happy to carry the fob separately, but it matters if you normally keep your car key, house keys and other essentials together. This guide explains the sensible options, how to avoid damaging the original fob and what to consider when storing a keyless-entry key at home.
Important: Jaecoo key designs and supplied equipment can differ by model, derivative and build date. Check the actual shape, buttons and emergency-key arrangement of your own fob before buying or fitting anything. This is independent general information and does not replace the vehicle handbook or instructions supplied with an accessory.

Why the Jaecoo key can be awkward to attach
Many people expect a car key to have a hole or metal loop through which a split ring can be threaded. If your Jaecoo fob uses the common smooth-edged smart-key design, there may be no obvious external attachment point on the original casing.
The removable mechanical key concealed inside a smart fob is an emergency-access component, not a convenient place to improvise a keyring connection. The release mechanism and the joins in the plastic casing should also be left unobstructed.
Do not modify the original fob. Drilling the casing, gluing on a loop or forcing a ring into an opening could damage the shell, interfere with the emergency key, compromise protection around the electronics or make a future battery change more difficult.
Practical ways to carry your Jaecoo key
1. Use a fitted cover with an attachment loop
A model-specific cover can protect the original casing while supplying the missing attachment point. The key remains complete and unmodified inside the cover, while a loop on the cover accepts a small split ring, clasp or wrist strap.
This is normally the most convenient option for someone who wants the fob attached to house keys. If you choose it, the important part is compatibility rather than appearance. Browse the available MyJaecoo key-cover designs and compare each listing carefully with the key in your hand.
2. Carry the fob in a small key pouch
A zipped pouch or separate compartment protects the fob without connecting it to anything. This can suit keyless entry because the key normally remains in a pocket or bag while the vehicle is being used. Make sure the pouch does not hold the buttons down accidentally.
3. Keep it separate
There is no requirement to attach a smart key to a larger keyring. Carrying it separately avoids extra weight and bulk, although it also means developing a reliable routine so the fob is not left behind or put through the wash.
Choosing the correct key cover
A product described simply as a 'Jaecoo key cover' is not automatically suitable for every Jaecoo. Before ordering, compare:
- The outline of the fob: check the length, width, corners and side profile.
- The number and position of the buttons: the cut-outs or button markings must match your key exactly.
- The emergency-key access: the cover should not prevent the mechanical key from being released when needed.
- The attachment point: check whether it accepts the ring or clasp you intend to use.
- The construction: some covers stretch over the key, while rigid designs may separate into sections and use small retaining screws.
Use photographs of the complete front, back and sides of the actual key rather than relying only on the vehicle's model name. If two key shapes are shown in a listing, select by physical match and button layout.
A key cover is only an outer accessory. It does not include a programmed remote, replace a lost key or repair damaged electronics.
Fitting a cover without damaging the key
Follow the instructions for the particular cover. For a rigid screw-together design, the usual process is to remove the small retaining screws, separate the cover sections, place the complete original key inside, align the sections and reinstall the screws.
- Work over a clear table so the small screws cannot disappear.
- Use the correctly sized screwdriver and avoid marking the screw heads.
- Do not dismantle the original Jaecoo fob, only open the accessory cover.
- Check that the buttons, indicator area and emergency-key release align correctly.
- Tighten the cover screws evenly and only until secure. Do not overtighten them.
- Test every button and confirm that the vehicle still detects the key normally.
- Attach a small ring or clasp to the cover's intended loop, not to another opening.
If the parts do not sit together easily, stop and recheck the orientation and compatibility. A correctly matched cover should not need to be forced around the fob.
Everyday care and keyring weight
A cover can reduce cosmetic damage from drops and contact with other keys, but it does not make the electronic fob indestructible or waterproof. Keep it away from liquids, excessive heat and situations where the buttons could remain pressed.
Use a modest keyring rather than hanging a heavy collection of tools, tags and decorative items from the cover. The Jaecoo uses push-button start, so this is not the old concern about weight hanging from an ignition barrel but about about avoiding unnecessary strain on the cover's attachment loop and keeping the fob comfortable to carry.
Periodically check that:
- small cover screws remain secure
- the split ring or clasp has not opened or distorted
- the cover is not pressing a button
- the emergency key can still be accessed
- the fob is still detected reliably by the vehicle
Keyless-entry security at home
Some Jaecoo models use passive keyless entry and start, allowing the vehicle to detect a nearby smart key without the owner pressing its buttons. The official UK Jaecoo specification should be checked for your exact model, while the Jaecoo Download Center provides current owner manuals.
Relay theft uses electronic equipment to make a vehicle behave as though its key is nearby. Thatcham Research recommends signal-blocking storage for passive keyless-entry keys, including the spare, and checking whether the vehicle's keyless function can be disabled. UK police guidance also recommends keeping keys away from the vehicle, doors and windows and checking signal-blocking storage regularly.
A practical routine is to place both keys in secure signal-blocking storage when you arrive home. If a household wants one container for several keys, a Faraday key box could be a good option.
How to test signal-blocking storage
- Place the key inside and close the box or pouch exactly as instructed.
- Carry the closed container to the vehicle.
- Check whether passive entry still unlocks the car.
- If safe to do so, confirm the vehicle does not detect the enclosed key for starting.
- Repeat the test periodically because wear, gaps or an incorrectly closed lid can reduce effectiveness.
Signal-blocking storage is not a guarantee against vehicle theft and does not address every theft method. Lock the vehicle, confirm it has actually locked, keep valuables out of sight and consider visible physical security where appropriate.
New-owner and spare-key checks
While collecting the car, check how many keys are being supplied and test all of them. Learn how the emergency mechanical key is released and where the handbook says it should be used if the smart-key battery is depleted.
Keep the spare somewhere secure, but never inside the vehicle. Avoid attaching anything to either key that displays your home address, registration number or other information that could connect a lost key to the parked car.
If a used vehicle is supplied with a key missing, ask an authorised repairer or retailer about deleting the missing key from the vehicle and programming a replacement. Thatcham specifically recommends dealing with a missing working key rather than assuming it can no longer access the car.
Quick Jaecoo key questions
Do I need a cover for my Jaecoo key?
No. The key works without one. A fitted cover is simply a practical option if you want protection and an attachment loop for a ring, clasp or strap.
Can I drill a hole in the original key casing?
Do not drill or otherwise modify the original smart-key casing. The fob contains electronics and an emergency-key mechanism, and external damage could make it unreliable or difficult to service.
Will a key cover stop keyless entry working?
A correctly fitting cover intended for the key should not prevent normal operation, but materials and designs vary. After fitting it, test every button, passive entry and vehicle starting. Stop using the cover if detection becomes unreliable.
Can I attach all my house keys to the cover?
You can attach other keys if the cover is designed for it, but keep the bunch reasonably light. Excessive weight and bulk can strain the accessory loop and make accidental button presses more likely.
Should the spare key also go in a Faraday box or pouch?
Yes, if the spare also transmits a passive keyless-entry signal. Thatcham and police guidance specifically includes spare keys when recommending signal-blocking storage.
Does a Faraday box guarantee the car cannot be stolen?
No. It is intended to block the key's signal and reduce relay-theft risk while correctly closed. It does not prevent every possible theft method, so it should be treated as one part of a wider security routine and tested regularly.
Can a protective cover replace a damaged or missing key?
No. A cover contains no programmed electronics. A damaged, missing or unreliable smart key should be assessed by an authorised Jaecoo retailer or suitably qualified automotive locksmith.
Final takeaway
The absence of an obvious keyring eyelet is inconvenient, but it does not require any modification to the original Jaecoo fob. Decide whether you actually need the key attached to anything and if you do, choose a correctly matched cover with its own purpose-built loop, fit it carefully and keep the attached keyring light.
Then treat storage as part of the same new-owner setup. Keep both keys secure and away from doors and windows, test any signal-blocking container periodically and follow the handbook for the specific smart key supplied with your vehicle.
