Is an immobiliser annoying to live with day to day?

For about a week. Most people forget the sequence once or twice at the start, and by the second week it sits in the same mental category as putting a seatbelt on. Most tell us they have stopped noticing it entirely within a month.

What if somebody else needs to drive my car?

Regular drivers need the sequence, so keep it short and teachable. For an occasional driver use valet mode, which lets somebody start and drive the car for a limited period without learning your sequence — settable from your phone on a CAN Phantom.

Can I change my disarm sequence later?

Yes, whenever you want, and you should if somebody who no longer needs it knows it. On a CAN Phantom you can do it from your phone in under a minute.

What happens if I forget my sequence?

You are not driving anywhere until it is sorted out. It is rare and it is recoverable, and it is the trade you make in exchange for a car that a thief holding your actual key still cannot move.

What it is like to live with an immobiliser in Northampton

By Kaine Carter10 September 20266 min read

Almost every Northampton driver asks the same question before booking, and it is never about relay attacks. It is some version of: am I going to find this annoying? It is a fair question and it deserves a straight answer rather than a sales one, because a system that irritates you is a system you will stop using.

The first few days are the awkward part. You will get in, start the engine, pull off the drive and stall — or rather, discover the engine turning over and not firing, because you have not entered the sequence yet. That happens to nearly everyone in the first week and it is genuinely the worst of it. By the end of the second week it has moved into the same mental category as putting your seatbelt on: something your hands do while you are thinking about something else. Most people tell us they stop noticing it entirely by the end of the first month.

What makes the difference is the sequence you choose, and it is worth a minute of thought rather than picking something at the kerbside. It is entered on buttons the car already has — steering wheel controls, window switches, the pedals — and it can run to twenty presses. Almost nobody wants twenty. The advice we give is to pick something short enough that you can do it one-handed while putting your belt on, using buttons that are comfortable to reach in a normal driving position, and to avoid anything with a meaning behind it. No birthdays, no house numbers, and nothing that traces an obvious pattern somebody could pick up from watching once through a windscreen.

Then there is everybody else who drives the car. A partner, a son or daughter, whoever borrows it to fetch something — they all need the sequence, and there is no way round that. On most households this is fine because the sequence is short and everybody uses the car regularly. Where it needs thought is the occasional driver, and that is what valet mode is for: it lets somebody start and drive the car for a limited period without ever learning your sequence, and then it lapses. On a CAN Phantom you can set that from your phone, which is the single most useful difference between the two systems day to day.

Garages and dealers are the other situation, and it comes up sooner than people expect. A technician who cannot start your car will ring you from the service desk while you are at work, which is a conversation nobody enjoys. Ghost II has a service mode for exactly this and the Phantom has its timed valet mode. Learn how to use it before the first booking rather than during it — we show you on fitting day for that reason, and it is worth paying attention to the ten minutes even though you will not need it for six months.

A few smaller things people ask. You can change your sequence whenever you want, and you should if somebody who no longer needs it knows it. Nothing lights up on the dashboard and there is no box anywhere visible, which is deliberate — the whole value is in a thief not knowing why the car will not start. There is no subscription and no app you are obliged to keep. Battery drain is not a real concern, because the standing current is well below what the car's own alarm and central locking already draw.

The one honest downside is that if you forget your sequence, you are not driving anywhere until it is sorted out. It is rare, it is recoverable, and it is the trade you are making in exchange for a car that a thief with your actual key still cannot move.

If that sounds workable, send us the registration and we will confirm which of the two suits your car, with a written price before anything is booked. We fit across Northampton and the surrounding NN postcodes on your own driveway.
