Lexus RX Key Replacement | Mobile Help For Missing Smart Keys
For an RX 450h key concern, the 12-volt battery check comes first. Our mobile Lexus RX key replacement service also covers spare keys and all-keys-lost cases, including newer models.
- Mobile service at the vehicle
- No upfront payment
- Compatibility checked before attendance

The Hybrid Check That Comes First
If you are reporting a Lexus RX smart key problem on an RX 450h, tell us that it is the hybrid when you call. The first check is the 12-volt battery; the enquiry should not begin with an assumption that another key is necessarily the answer.
Describe what is happening and whether you still have any keys. We can then discuss the battery check alongside your request, rather than overlooking it. This is separate from a straightforward lost RX key enquiry, where the immediate need is to replace something that is no longer available.

RX Key Programming Across The Generations
Our Lexus coverage includes replacement keys at the vehicle, with no dealer-only restriction for newer RX models.
AL10 and AL20
The AL10 dates from around 2009–2015, while the AL20 follows from approximately 2015–2022. Give us the registration if you are unsure which generation you own; there is no need to identify it before asking for help.
More recent vehicles
Newer generations are covered for spares and all-keys-lost work too. Our car key programming service takes place where the vehicle is parked, so RX key programming does not require a workshop visit.

What If Every RX Key Has Gone?
We can make replacement keys at your RX even when none remain. When arranging help with lost car keys, provide your location and registration, and say plainly that there is no remaining key. Home, workplace and car park visits are all part of our mobile service.
Before making a key, we must see your V5C and photo ID. The price is provided before travel, without an upfront payment. Should the work turn out differently, we explain any revised price before proceeding; you can decline it without a call-out charge.
