Can a Dealership Sell a Car Without a Spare Key?
Yes. No UK law requires a car to be sold with two keys, so a dealer can lawfully hand over one, and what the law does bite on is the description, because an advert that promised two keys becomes a term of the contract. That single distinction decides every version of this question. A car advertised with two keys and delivered with one is a description failure under the Consumer Rights Act 2015, and the short term right to reject runs for 30 days from the day you take the car. A car disclosed as having one key before you signed is a disclosed condition rather than a fault, and the remedy there is the price rather than the law.

Where the law sits, in four situations
Two keys is a convention of the trade and a commercial expectation. It is not a statutory duty, and nothing in consumer legislation, government guidance on buying a used vehicle or the vehicle security regulations sets a key count. The duty that does exist is accurate description and no concealment.
Find your situation in the table, because the route you have depends entirely on what was said before the money moved.
| What happened | Legal position | What you can do |
|---|---|---|
| The advert or order form said two keys and one arrived | A description failure, because stated specification becomes a term of the contract | Put it in writing, quote the advert, and keep the 30 day short term right to reject as the backstop |
| One key, stated or plainly visible before you signed | A disclosed condition, which sits outside the satisfactory quality term | Negotiate the replacement cost off the price before you sign anything |
| One key, nothing said either way, noticed after 30 days | Inside six months the trader carries the burden of showing the car was as described | Raise it in writing and ask for the key or the cost of one |
| Private sale where the advert said two keys | As described still applies to a private seller, even though satisfactory quality does not | The advert wording is the evidence, so keep a dated copy of it |
Nothing in that table turns on how many keys the car has. It turns on what was said before the money moved.
No approved used scheme promises two keys
A survey of every manufacturer approved used scheme in the United Kingdom, 41 of them, found no key count commitment in any single one. Those schemes publish detailed inspection point counts, ranging from around 111 points to 201 points depending on the badge, and not one of them publishes a key requirement.
The only key related entry anywhere in that list is one scheme that bundles key insurance, which is cover against losing a key rather than a promise about how many arrive with the car. So an approved or certified used badge is not evidence of a spare, and the question still has to be asked and written down.
The questions to ask before you sign
Each item below is a lever that exists in law or in the industry sales code, and each one takes seconds at the point where it still costs the dealer something.
- Ask how many keys come with the car and have the answer written on the order form, because a stated specification becomes a contract term.
- Ask for the pre sales checklist, which an accredited business hands to you before the point of sale.
- Test both keys on the car at handover. Lock, unlock and start with each one before you drive away, because that responsibility sits partly with the buyer.
- Keep a dated copy of the advert, including the photographs and the specification list.
- Where one key is disclosed, price the replacement for that exact model and take it off the offer rather than accepting a vague promise.
- Refuse sold as seen wording. The industry sales code prohibits statements that appear to reduce your legal rights, and the legislation bars contracting out of them in any event.
What a missing key costs at part exchange
Trade valuation guidance lists spare keys alongside parcel shelves, spare wheels, inflation kits, wheel braces and book packs as items whose absence makes a car look neglected, states that spare keys add to the perceived value, and notes that buyers factor the replacement cost into the offer. One volume buyer states its policy outright, that it buys cars with one set of keys at a reduced valuation and does not buy cars with no keys at all.
No published figure exists for the deduction, because it is not a fixed number. It tracks the replacement cost for that specific car, which is why it ranges from a modest amount on an older bladed key to several hundred pounds on a smart proximity key.
Pricing a second key before the part exchange settles that figure, and on an older bladed key the job is car key cutting on its own.
| Key type | Typical cost of the key | Programming, charged separately |
|---|---|---|
| Traditional mechanical blade | £50 to £90 | Not required |
| Basic remote key | £70 to £130 | £50 to £100 |
| Transponder key | £90 to £180 | £70 to £150 |
| Flip style key | £100 to £220 | Priced as a remote or transponder key |
| Smart or keyless proximity key | £150 to £350 and above | £120 to £250 and above |
Those are typical ranges rather than a quote. The figure for a specific car depends on the model, whether a security code has to be requested from the manufacturer, and when and where the work is done.
If a promised key never turns up
Speed is the whole game here. The strongest remedy expires 30 days after you take the car, and a buyer who waits four years to raise it has nothing left to use.
- Put the request in writing, quoting the advert or the order form and naming a date for supply.
- Ask for the second key to be supplied or funded, in writing, and keep the reply.
- Inside 30 days of taking the car, the short term right to reject and a full refund is the backstop, so act inside that window rather than negotiating past it.
- Inside six months, the trader carries the burden of showing the car was as described, which is a strong position to put in the letter.
- Where the dealer refuses, check whether they are accredited to a motor industry dispute resolution scheme and use it.
- After that, the trading standards route through the national consumer advice service.
What insurers and the log book do not record
The V5C has no bearing on this question at all. The checks it is used for on a used purchase are the watermark, the serial number against the stolen document ranges, whether the details match what the seller told you, and whether the vehicle identification number and engine number match the document. Keys are not among them and the V5C records nothing about them.
No insurer requires a car to have two keys, and nothing supports the idea that one key raises a premium. What an insurer does care about is where the keys were at the time of a theft, which has decided claims, and on a total loss it asks for any spare key along with the remaining V5C sections and the MOT certificate. That is a practical reason to know where the second key is, rather than a legal one.

Frequently Asked Questions
Call 07308 888825Can a dealership sell a car without a spare key legally?
Yes. No UK law sets a minimum number of keys, and the industry code body states directly that a dealer is not legally obliged to provide two keys. The obligation is accurate description, so the position changes the moment an advert or a salesperson says the car comes with two.
Do new cars always come with two keys?
Two keys is the normal supply on a new car from a franchised dealer, and it is a trade convention rather than a rule. Check the order form, because the specification written there is the one that binds, and raise a missing second key before you take delivery rather than after.
Are used cars supposed to come with two keys?
There is no legal requirement and no manufacturer approved used scheme that commits to it. One key is a normal condition on older and cheaper stock, and a dealer disclosing it is behaving correctly. Treat it as a priced item in the negotiation rather than as a breach.
Can I ask the dealership for a discount if there is only one key?
Yes, and it is the standard way the trade handles it. Trade buyers reduce their valuation for a missing key, so the same logic applies in your direction. Price the replacement for that exact model, including programming, and ask for that amount off or for the dealer to fund the key.
How much does a replacement car key cost?
It depends on the key type. A plain mechanical blade runs from around £50 to £90, a basic remote key around £70 to £130, a transponder key around £90 to £180, a flip style key around £100 to £220, and a smart or keyless proximity key from around £150 to £350 and upwards, with programming charged on top for everything except a plain blade. The figures by key type are set out under car key replacement.
What should I do if the dealership promised a spare key but did not provide it?
Put it in writing straight away, quoting the advert or the order form. A stated specification is a contract term, so a car described with two keys and delivered with one is not as described. The short term right to reject and a full refund runs for 30 days from the day you took the car, and inside six months the trader has to show the car was as described.
Does a certified pre owned car come with two keys?
Not as a guarantee. A survey of all 41 manufacturer approved used schemes in the United Kingdom found no key count commitment in any of them, and the only key related benefit anywhere in that list is key insurance on one scheme. Ask the question and get the answer in writing rather than relying on the badge.
Can I make a spare car key myself?
No. A plain mechanical blade can be copied, and any key carrying a transponder or a remote has to be programmed to the vehicle with equipment that reads it. A copied blade opens the door and never starts the engine, which is why a spare cut while you still hold a working key is the cheap moment to do this. A second key cut and matched to the vehicle is spare key creation, and it is finished where the car stands.
Does one key affect my insurance?
Not the cover itself. No insurer requires two keys and nothing supports the idea that one key raises a premium. Where keys matter to an insurer is a theft claim, where the location of the keys at the time has decided cases, and a total loss settlement, where the insurer asks for any spare key to be handed over.
