    What to Do if You’ve Lost Keys to Your Bike Lock

    1. Don’t panic. You may be able to find the lost keys.

    It’s important to remember if you’ve lost a set of keys, that they can’t have disappeared into thin air. They will be out there somewhere and if you think it through, you should be able to find them.

    But the faster and sooner that you start looking, the better your chances are of finding them!

    If you’ve already searched everywhere for your keys, have a read of my article which teach you how to remove a bike lock without keys.

    Note that the steps in this separate guide are unlikely to work on top-of-the-range bike locks, but are definitely worth a try before attempting any irreversible methods.

    I know exactly how it feels. As much as you want to scream and shout, don't panic. Acting quickly to retrace your steps will increase your chances of finding your lost bike keys.

    2. Double Check Places Where You’d Normally Leave Your Bike Keys

    I can’t tell you how many times I’ve thought I’ve lost my glasses, only to realise they are on top of my head. So, if you’ve lost the keys to your bike lock go through the places that you’d normally leave them.

    Before you start trying to cut your bike lock off or decide on purchasing a new lock, have a good thorough search of the areas listed below:

    Around the Area Where Your Bike Is/Was Locked

    When locking or unlocking your bike, you may have accidentally dropped the keys on the floor, or placed them down and forgot to pick them up.

    If you did, someone may have found them and handed them in, or they may have left them nearby somewhere visible. Have a good look around the area and don’t be afraid to ask in shops/office receptions nearby.

    Jacket/Coat/Trouser Pockets

    By far one of the most common places to leave bike keys, the pocket. Try to remember what you were wearing around the time you can last remember having your keys.

    Are they in a dirty pair of jeans or in your raincoat hanging up?

    Check all of the pockets!

    Another popular place to keep keys & valuables. Have a good look around inside, even if they are not in the normal area of your bag that you keep your keys in.

    They may have fallen to the bottom of your bag or you may have put them elsewhere in your bag by accident or in a rush.

    At Home

    Normally when you lose your keys they’re somewhere around the house. Have a check in-between the sofa cushions, in your bedroom, at the bottom of your laundry basket.

    If you have a key drawer/box/hanger have a good look here too, it’s worth checking anywhere.

    At Work

    When rushing home to avoid the traffic it can be easy to forget to take things with you.

    You could have left your keys on your desk, or in your locker at work.

    Have a good look in and around the areas where you'd normally leave your bike keys.

    3. Ask People You’d Been Around Before Losing Your Bike Lock Keys

    If you last remember having them at work it may be worth asking colleagues if they’ve seen a set of keys lying around anywhere.

    Do the same if you had been at a friend’s house. Someone you know may have seen them but not realised they were the keys you lost for your bike lock.

    4. Check if You Have Spare Key for the Lock

    All reputable bike lock manufacturers will send more than one key with their locks.

    You may have purchased your bike lock a long time ago, but it’s worth trying to remember if you received a spare key with it. If you did receive a spare key, it’s time to start looking for it.

    5. Check if Your Lock’s Manufacturer Offer a Key Replacement Scheme

    ABUS & Kryptonite both offer key replacement services to their customers. OnGuard also offer a key registration scheme, but only to customers in the USA which is a shame.

    When you purchase a bike lock from a reputable manufacturer you’ll normally receive some sort of key-card.

    This card will have a special code on it that should be kept private as this code enables you to get new bike keys cut for your lock.

    Hopefully, you kept this when you bought your as it will come in handy if you’ve lost the keys to your bike lock.

    Kryptonite Key Safe Program

    To be able to use the Kryptonite Key Safe Program, you must have one of the following models of locks:

    • New York Fahgettaboudit U-Locks and Chain Locks
    • New York U-Locks, Chain Locks, Disc Locks
    • Evolution Series 4 U-Locks
    • Disc Locks, Evolution Mini U-Locks
    • KryptoLok Series 2 U-Locks
    • Hardwire Cables and Kryptoflex Cables

    If you’re unsure if you have access to the Key Safe Program, check the box your lock came in.

    Otherwise, you could also search for your lock’s model on the Kryptonite website or ask someone on Kryptonite’s customer forum.

    If you use one of the above locks and are ordering new Kryptonite Keys, you will need the key number. This number is found on your lock’s keys, which isn’t what you want to hear at this stage.

    However, the key code can also be found on a small tag that is on the keyring that your original keys came on. You will need this key code to order new keys.

    Kryptonite Replacement keys cost $12 for 1 key, $20 for 2 keys and each additional key on top of this is an extra $5. They offer free worldwide shipping on all replacement keys

    ABUS Additional Key Service

    Your ABUS Code Card Will look similar to this and was supplied when you first purchased your bike lock.

    ABUS also offer a lost key replacement service. You can order new bike lock keys from your local specialist retailer.

    Much like Kryptonite Keys, when you purchased your lock you should have received a security card which has a code on it that enables new keys to be cut.

    On their website, you can use the dealer search tool (follow the link above) to find your nearest specialist dealer. Keys normally take a few days to be delivered.

    If you lost the keys to a good quality bike lock you’ll save money by getting new keys cut rather than purchasing a brand new bike lock.

    6. Consider Upping the Security of Your Bike if It’s Locked Whilst Waiting for Replacement Keys

    If you’ve managed to order replacement keys the likelihood is that you’ll be waiting a few days for them to arrive.

    It’s now worth thinking about the security of your bike if you were unfortunate enough to lose your bike keys whilst it was locked up.

    If you lost keys to a lock that isn’t secured to your bike, count yourself lucky. You can skip this step and move onto step 7.

    If you're waiting for replacement keys, and have spare locks available, use them to increase your bike's security whilst it's locked. Make sure you keep the keys safe, or you may be in some trouble!

    If your bike was left secured in a busy public place you will want to prevent thieves from either stealing it completely or taking its components.

    I’d recommend that you remove any valuable components that aren’t properly secured. Or use a good quality bike lock to secure any components you cant remove.

    Normally the frame and wheels are the most valuable parts, so take what you can home with you whilst you wait for your replacement bike keys to arrive.

    If you have to do this, it can be very helpful to have proof of ownership of the bike.

    If someone sees you removing components from a locked bike they may intervene and try to stop you, which is completely understandable.

    Proof of ownership could be the original purchase receipt, a picture of you with the bike, or a logbook with matching serial numbers. If you have proof the bike is yours take it with you just in case.

    Before we attempt to remove your bike lock, there are a few ways to unlock a bike lock without keys.

    These methods are more effective on old, cheap bike locks. Definitely worth a try though!

    If you haven’t already, check out this short guide.

    7. Remove the Lock if It’s Securing Your Bike and You Can’t Get a New Key        

    If you’ve lost the keys to a bike lock that is currently securing your bike, and haven’t been able to find/obtain a spare key, you’ll most likely have to cut it off.

    Only attempt this yourself if you know what you’re doing and have the correct tools & safety equipment.

    If you are not capable of removing the lock yourself, a local bike shop or hardware store may be able to do it for you.

    Normally this will cost a small amount, and they will require proof that the bike is yours, so have this ready to prove the bike is yours.

    It’s important at this stage to think about where it is secured. If your bike is secured on private property, it’s good practice to inform the landowner of what you’re planning to do.

    The landowner may be able to assist you in removing the lock. It’s also important to tell the landowner so that they know you aren’t a thief!

    Bike thieves use bolt cutters to steal bikes
    If someone saw this, it's likely that they'd call the police or attempt to stop you. If you're going to remove your bike lock make sure you bring proof that it is your bike!

    If your bike was secured in a public area, it could be worth informing the police of what you’re doing via a non-emergency number (in the UK this is 101).

    By informing the police if anyone reports you, they will understand what is going on and nothing should come of it.

    Again if you are removing the lock of a bike without the keys it’s worth having proof of ownership on you, to prove you’re not stealing!

    8. Get a Good Quality Bike Lock & Get Back Out There!
